I used to use the elementary file manager and it was great... Then they started adding features that were really bad. Like they would try to calculate the size of a directory and its contents when you would just hover over the directory. For a directory with a lot of files that can be a CPU intensive task. My file manager was literally pegging one of the cores on my poor already overworked pinebook pro. For a feature I didn't ask for and which had no way to be disabled from the ui. Not wanting to poke around dconf, I tried a handful of file managers and settled on nemo. It just works, has a decent number of toggles, is leightweight. The familiar name was a bonus ;) The one thing I miss from elementary's file manager is the column view.
