I've seen their page and while it seems great, I don't think they'll match Jetbrains in term of out of the box ergonomics. Could be a good VScodium replacement once it gets a bit fleshed out and available on Linux.
All of the above, and I ran into some bugs in Datagrip that when I reported them I was blown off and gaslit in the response. The response to the bug report was something like "No one does things like this, and even if they did it isn't important" MF, I DO IT, and it was important enough for me to report the bug!
That was enough for me to not renew our licenses for our team when it was time to re-up.
Bulky. It has so many features and many times, it's missing just one or two more things from being good enough. Its like Excel, where it tries to predict/outsmart the dev but all that does is annoy them.
I'm not a fan of Rider, it's just that OmniSharp outright breaks on large/real-world projects and Visual Studio doesn't work on Linux. I don't use their products out of choice.
Man I wish OmniSharp didn't suck. I built an extension with VSCode and got excited about what I could build, looked into OmniSharp again and gave up when it was crashing without me even throwing a big project at it.
