As a paying user of Sublime Text 3, I finally jumped on the Atom bandwagon a few months ago and have overall been pretty happy.
It's certainly a slower editor - I have found that opening it, creating a new window, and quitting all take more time than I would like. However, I have stuck it out primarily for two reasons:
1. It's far more extensible. Sublime Text has a thriving package ecosystem, but the limitations of the extension API show up in lots of little places. Atom being browser-based comes with its downsides, but it also allows flexibility that Sublime could only dream of.
2. It's open source. Sublime Text is a great editor, but it's closed source, maintained by a single guy, and updates have slowed to a crawl. It's not something I ever felt 100% comfortable with relying on as part of my day-in-day-out workflow.
