File Browsers: Files AND Dolphin
I use both Dolphin and Files for some years, Each have some excellent features (and can be run at the same time)
Files allow you to eject your data DVD/Memory Stick with great ease and Dolphin (as installed using 'Terminal', and gives better information detail. The is another Dolphin one that is truly terrible !)
Don't know anything about the others... Dolphin is by far the better.
