I really keep trying to use Atom, but it's just unacceptable currently when compared to Sublime. Very slow startups and laggy. This new version takes 5-10 seconds before I can start coding, that's far too slow. With every update I keep hoping things are faster, but only marginally so. VS code loads in less than 3 seconds and is a lot more snappy.
I don't understand why they don't address this issue as the highest priority problem. It's by far the most complained about issue. If the MS guys can make VS code launch that fast I don't see anything holding back Atom (save maybe coffeescript :P (tongue in cheek)).
