Not sure about cursor. But if you want to use Claude Code daily for more than 2-3hrs/day, the $20 plan will feel limiting

In my experience, the $100 plan is pretty good, although you still run into the rate limits if you use it for a long time everyday (especially if you use Opus, which seems to run out in the first 30min of usage)
