You're gonna have to take my word on this: Consulting gets significantly less stressful past year 3. The entire point of the industry is that you "abuse" fresh grads with work in exchange for them getting a "big" name on their CV. Past year 3 you either get promoted very quickly(consulting pay scale is like an S-curve Edit: Its more like an S-curve and then a lottery, because once you are on the "partner" track past year 6-7 its a crapshoot and if you don't want to play its better to exit) and will get to chill out a bit more, or you exit into the industry into a cushy job.
If you are not interested in academia, do not go for PhD. You will absolutely hate having to do TA for random subjects for shit pay.
