Many people don't explicitly for this reason. I know I can't, its just too much stuff stuck together. I'd expect something like VS and Atom to be made well polished and optimized. The projects are rather large and both have well staffed teams behind them. I'll take sublime, eclipse, or even JetBrains products over VS/Atom because those editors/IDEs are polished and simple to use. I don't need to RTFM just to add three lines to a text file.
