First of all, congrats! I am a 2023 alum of Lawrenceville. Don’t go to Andover because you think it’s more prestigious; the lifestyle at both schools are very different.
What specific comparisons are you looking for? The general impression I’ve gotten from my interactions with Andover students, both while in HS and college, is that it is very cutthroat—much more so than Lawrenceville, which is suprising. I also felt a bit of a superiority complex from some of my interactions, but I wouldn’t generalize that too much.
I personally absolutely adored my time at Lville and would not trade it for anything else. Even though my class went through pretty much everything terrible that could happen to us (Covid, May 2022, etc.), I mostly look back fondly on those days.
I do agree that Murray is tone deaf, but the rest of the faculty makes up for it.
