pro is the $20, right? It runs out quickly, especially using opus. But what do you expect for that kind of money? For serious work at least Max $100 is needed.
Claude's subscription model is forcing you to space out equal sessions unnaturally during day - but you don't work like that. You work N hours of day and then go to have personal life/sleep - meaning you sometimes code more and sometimes you don't. Forcing you to do only little work and then lock you out for extra usage will make you pay much more when actually using the model much less - because the times you are not coding would even out or even benefit you in credits
Tl;dr - it's claude's greedy credit system that sucks, i am not going to pay $100 for overcoming these weird limits, i would much rather use gemini cli
