On my side I have used Claude code, tbh for solo projects it's good enough if you already know what you need to do.

Answering your questions:

On my job we've been spoon fed to use GH copilot everywhere we can. It's been configured to review PRs, make corrections etc. - I'd say it's good enough but from time to time it will raise false positives on issues. I'd say it works fine but you still need to keep an eye on generated BS.

I've seen coworkers show me amazing stuff done with agentic coding and I've seen coworkers open up slop PRs with bunch of garbage generated code which is kind of annoying, but I'll let it slide...

Stack - .NET, Angular, SQL Server and ofc hosted in Azure.

Team is composed of about 100 engineers (devs, QA, devops etc.) and from what I can see there are no Juniors, which is sad to see if you ask me
