I wholeheartedly agree that Nemo provides a far better experience than Nautilus.
But Nemo is also not without issues. Crashes when deleting files in certain situations (folder tree is expanded and you delete all files). If you are using Nemo and use a lot of network drives or external drives, be prepared for random freezes.
When that freeze happens, killing Nemo doesn't help, nemo -q doesn't help, restarting cinnamon doesn't help. That's when I fire up the ol' trusted Thunar.
