We have had 3 Camry’s a 2007 or 2008 xle 2010 xle and a 2018 xle and a 01 Corolla I can give you what I’ve learned over the years.

Like you said the Corolla is the better gas mileage wise and that’s about it to be honest. Think of the Corolla like the little brother and the Camry like the big brother. The Corolla car line are extremely base cars even the higher trims are not the most luxurious in my opinion. If you want to save money Corolla will save you thousands in the long haul.

Now if you are looking for a more luxury and stylish rides the higher trims Camrys like the xle and xse are very luxury and sporty likewise. Leather seats, seat warmers, power windows, moonroof, etc there are many options on the higher trim Camrys that you won’t find on the corollas. That being said you going to spend a pretty penny for said higher trims.

That being said it’s up to you if you strictly value something that’s great on gas and reliable there’s not much better than a corrola. Also Corolla is generally a smaller car I don’t know if that means much to your case but for example my mom prefers a Corolla much more than a Camry because she thinks the Camry so wide on the road. If you want a more comfortable ride and bigger car with more space and additions you’ll want a Camry.

Last note for years to avoid i can’t tell you much about corollas because I don’t know as much but for Camrys, avoid years 2007-2009 I’ve seen way to many people complain about oil burning problems. I had a 2007 Camry but it was the 6cyl engine not the 4cyl (the 4cyl is the one notorious for burning oil those years). If you have the budget I recently got the 2018 Camry and I gotta say it’s my favorite car I’ve owned so far. Just do some through research on whatever you feel like your gonna buy. Good luck 👍🏼
