UC Irvine (Undeclared) or UCSD (Undeclared)

[Californian10]

I have been admitted to both UCs, but the problem is, I was not given my major for both (Computer Engineering). Which UC would it be easier to transfer into the engineering program? I am in a dilemma and I simply don’t know which one to choose. I also heard that it’s nearly impossible to transfer into Computer Engineering in UCSD. I was assigned to Sixth College as well in UCSD. Which is the better UC to transfer into engineering?
