You will receive an excellent education at all schools. Congratulations on your acceptances!
We can’t speak to Loomis other than from the perspective of touring it a couple of years ago - so no comment. Kiddo did not apply there. You can tell by the avatar which school I was excited about = yes, Hotchkiss has it’s own 9 hole golf course - which is one of the best 9 hole public courses in the US. You walk out the door and there is a tee box. Both schools have strong golf teams and other excellent sports teams.
Deerfield & Hotchkiss have many things in common. Great schools that attract exceptional students from around the world. Beautiful setting in the countryside. Deerfield is in a valley rimmed by hills & mountains. Hotchkiss sits high above a valley with a beautiful lake. I think Hotchkiss has the most beautiful view and a concert hall with an amazing view. Deerfield also has an amazing concert hall, but not the stunning view. From people I know at both schools, I get the sense that Hotchkiss has a more robust music program.
Both Deerfield & Hotchkiss have fabulous athletic facilities. I think the new athletic center at Deerfield is more expansive : Indoor practice field(s), elevated running track, ice rink, indoor crew tank, golf simulator, dozen squash courts, team training & conference rooms, basketball courts, volleyball area, pool/diving, aerobics,spin, apparel store, etc. Here is a video of some of the facilities.

Both Deerfield & Hotchkiss are known for academic excellence. I know that Hotchkiss recently changed up their science curriculum. You should look at the course catalogues of both schools. Deerfield has several interesting STEM offerings in bio-engineering, neuroscience, electric car engineering, computer architecture, etc. Math curriculum at Deerfield is very rigorous & fast paced - many students find themselves highly challenged.
Deerfield has a Dance Company and several dance options for students who wish to participate as a dancer and in athlete in a dedicated sport. Student choreography is popular. Both schools offer architecture. Deerfield allows students to take it as early as Freshman year and later on you can take AP Architecture.
Both schools have many longstanding traditions and tons of spirit including big rivalries (Hotchkiss - Taft, Deerfield - Choate), bonfires, school songs, community gatherings, etc. Both pride themselves on their sense of community. Deerfield may seem more traditional. They have a school dress code that includes (Fall & Spring) wearing blazers. Deerfield has a sit down meals several times per week - one large round table with 8 or 9 students and faculty member. This is a great way to promote community building and friendships across class years. I think this contributes to a friendly vibe and allows for students to form connections with others from diverse backgrounds. We get the sense that Hotchkiss and Deerfield may draw students from slightly different NE areas, even though both schools have large international numbers. Deerfield has @650 students, grades 9 - PG from 49 countries.
You are fortunate to attend either school and will meet great people at both.
Do not get hung up on rankings - be a discerning reader of rankings and “top 10 lists”. Find the best fit for you so that you can be ? happy & thrive!
