DS accepted to GTech, UVA, Dartmouth, UCLA, Univ of Washington, Michigan. Waitlist at Princeton Dad’s undergrad; Stanford Dad’s grad B school…hope springs eternal for these to pop! 
He is brilliant, honest to a fault, wants engineering to sincerely make a difference in our messed up world–may be a different kind of Warren Buffet or Larry Page. Believe it or not…
Wow! That’s some diverse geography. Does that play a factor at all?
What about cost? Are all things equal?
Where to you live? Traveling home and visiting him may be more difficult for one or another.
Has he visited them all? Do any feel more like “home” to him? Will he “fit” at all of them?
They are all great schools, so academically, he’ll be off to a great start at any of them. So now… where will he be most happy (and you can afford and visit)?
Pretty different vibes as some of these schools. Hard to believe he doesn’t have a preference or two.
Yes to all the above comments…one of us is nearing retirement; the other is a highly needed high school teacher (read Math) and have the ability to purchase second home or lease something near where ever he ends up. Obviously the costs are concerning but we have saved and saved and saved for this eventual cost. Sadly we have made nice incomes but did not spend like we were never going to pay for college or retire (probably know only one couple more frugal than us and their brilliant son is picking college instate because of his girlfriend yikes.
So send your advice. Please!
I guess we need more help determining what to base the answer on. We know nothing about your son other than he’s brilliant. Does he like sun or snow? Does he like rural or suburban? Does it like the South? Does he want to do research? Are small classes important? Does each school offer the engineering major he is looking for? Does he want to live on campus one year? All four? Are all the schools roughly the same cost? I’d take out the most expensive 2 or 3 right off the top. If he’s not picky, which it sounds like he might not be, then pick by price. They are all great schools. (I personally would sway my kid away from UCLA due to difficulty getting classes and graduating in 4 years.)
Agree with @phoenixmomof2 All great schools, and he sounds like a great guy, but a little more info would be helpful. What is the net cost difference for you? Is he more introverted or extroverted? Does he like a more urban or rural environment? Is he interested in sports or other activities outside academics? What area of the country would he prefer? Does he prefer large or small? Independent self-starter used to navigating for himself? I mention this because larger schools don’t provide much hand holding or assign academic advisors. Would he want you to buy or lease a second home near whoever he goes? Do you mean for him to live in while there or for you to live in?
It should really be about what he feels is the right fit for him, and visits often quickly determine this. A place can seem like the perfect fit from everything you find on line, but you’ll read thread after thread of people who were sure they wanted to go to X university and feel completely differently after visiting. It’s almost like trying to buy a house in on line without ever seeing it. Looked great, sounded great, but in person it has no curb appeal and the neighbors are a nightmare. 
Great questions I wish he could say exactly. Hi I am very interested in continuing this conversation with you as I just read one of your threads…How is college going for your DD some 2200 miles away…? As for us–we are from the suburbs of Seattle…fairly large high school/football powerhouse but with very rigorous coursework. One of the most highly respected public high school in the state. Lots of professionals, high tech families, and great diversity from Europe & Asian also. Most are not too pretentious but there are some “big hat no cattle” types who spend over their means and I know I actually used to do their taxes until I went into teaching.
As a parent of two children who grew up in the “Seattle suburbs” in a competitive high school with a very diverse population, I think your son will be fine at any of the schools you listed. Both my children went east for school. They seamlessly entered new cultures/sub cultures of east coast living. I think growing up in an area so diverse allowed them to engage with all sorts of personality types effortlessly.
We have friends at four of the schools you listed and all have enjoyed academic success and are happy.
Best wishes to your son as he prepares for this next chapter. He was accepted to many, many fine schools! Congratulations.
I wish we had stayed in Northern Virginia he would have been soooooo happy at TTJHS. He definitely not a computer science type even though he already knows how to code fifth year requirement at Dartmouth gave him pause. He joked that “that was Harvard’s thing”. >:)
@mommamocha Would you mind terribly shaing son/daughter??schools??fields of study?? Have they returned to the West or are they staying out East? My parents (rest their souls how I miss them) were both from the East. Dad went to Hopkins just before WW2 then finished in 3 yrs and turned down Hopkins to go to Rochester med where he met Mom. She grew up in very poor immigrant family of 9 children but made it through college on scholarship and was one of three woman to graduate Rochester med in the early 1950s. Once done with school though they left and never went back except once each while I grew up. Spent nearly a month that Cornell was not for me even though I desperately wanted it. So I understand parent child relationships really well from many angles.
I’ll send you a PM. Would be happy to share.
You sure have a wonderful family story!
Bump
Has he visited any of the campuses in person? I will say that when we first Georgia Tech, it was the only one that talked about a life of service and giving back. It had a large impression on me at the time.
@southernhope. I hear you on that point. We have visited all. Still in a quandary but getting there…I hope.
