I personally much prefer using a local setup (editor+plugins+instantaneous compiling, etc), but of course collaboration is painful that way, especially given my collaborators much prefer web-based/shared work-flows. Just few days ago, however, discovered that I can use an overleaf project as just a git repo, then push/pull as I see fit. That is an amazing feature!... everyone get to work how they want. Hope that it stays included with the free version.
