I just tried Continue and it was death by 1000 paper cuts. And by that I mean 1000 accept/reject blocks.

And at some point I asked to change a pretty large file in some way. It started processing, very very slowly and I couldn't figure out a way to stop it. Had to restart VS Code as it still kept changing the file 10 minutes later.

Copilot was also very slow when I tried it yesterday but at least there was a clear way to stop it.
