I've been using Atom as my primary editor for over a year too, on various Linux distros, and it's been a very smooth experience. The only issue I've encountered is Atom can be sluggish with large (4MB+) files because it attempts to load the entire file into memory instead of streaming it like Sublime Text does for large files. Easy solution to it is to just use a plain text editor (gedit being my preference) to view your logs.
