Upvoter here. Nothing special -- I like Claude a lot. I found it more ergonomic to work with, and I think its models are state of the art. I believe I'm more productive especially in legacy crufty codebases.
I may not be representative of the universe or have a controlled, randomized study to back it up, but that's not what upvotes are for are they?
That's a fair point. To play devils advocate to myself, it's possible that the huge upvote share is due to a much bigger marketshare among our community.
