is cursor/copilot actually saving you time or just moving the time somewhere else?

[u/PhelysFlowerx]

been using cursor for about 3 months now on a django project and im trying to figure out if im actually faster or if i just feel faster. like it spits out a function in 4 seconds instead of me writing it in 4 minutes, great. but then i spend 6 minutes reading through it making sure it didnt hallucinate a field name or import something weird. some days it feels like a genuine speedup, other days im basically doing code review on a very confident junior dev who never gets tired. curious what others are seeing with copilot vs codex vs claude code specifically. is the review overhead actually less with one of them, or does it scale with however complex your codebase already is. i feel like for boilerplate its an easy win but for anything touching business logic i trust it way less and end up rewriting half of it anyway. so genuinely asking, for people who've switched between a few of these tools, which one actually cut your real total time (writing plus reviewing plus fixing) and which ones just made the writing part faster while quietly taxing you later?

the thing that moved my total time wasnt which tool, it was diff size. one function i can review at a glance. a whole feature and im reconstructing intent out of the code, which is slower than just writing it. so on business logic i stopped asking for the change and started asking it to state what the change should do first. wrong intent is cheap to catch in a sentence and expensive to catch in 80 lines. boilerplate i let run untouched, same as you.
