Residency was a million times better than med school.
I went to a small college, a huge medical school, and then a small residency. I liked college, and residency felt similar because low class sizes make it more comfy, more 1 on 1 time with attendings. Medical school was just too many people.
Residency was also better because you actually get a paycheck, if anyone is getting pimped it's the med students not you, and it's fun to actually work in your field of choice and learn useful things instead of be on rotations as a ms3 that you don't care about (except maybe if you have a separate intern year or off service stuff). Also attendings are generally nice and my co-residents are some of the best friends I've ever made (bonding thru shared suffering?), I'm sad I moved away but they're all going various places too after graduation.
The only part I struggled with was chronic sleep deprivation, and doing a 24-28 hour call shift is brutal. Carrying a pager sucked.
Good luck with the match! rank things in terms of where you'd honestly be happy to attend, don't go for prestige, nobody cares about where you went. Patients don't even know that residency is a thing they just sometimes ask where you went to medical school.
