I use Warp, and it's ok. I used iTerm with Fig before it but I was too cheap to pay for the AI features in Fig so when Warp offered that for free I switched. The AI is very useful. I'm someone who doesn't live in the terminal so I forget commands I don't use often, and AI neatly augments my 'I can almost remember but I need a hint' approach. But there are a few UI 'niggles' that would absolutely stop me paying for it (examples: focusing on a terminal with my mouse doesn't always put me on the command line if I click a history item instead, sometimes links in the history panels aren't option+click clickable for some reason, etc). It's certainly worth a try but it's a long way off being a Must Install app right now.
