I've been using it for several weeks and it's not bad. I'm just having some issues with video files synchronizing to the iPad.
The issue regarding deletion of files when doing a Reset is no big deal now that you know what happens.
Keep in mind your iCloud Drive Data is being backed up by Time Machine on your Mac.
I haven't had much problems in the couple weeks I have been using it either. Mainly using Numbers. I don't plan on using the reset all settings soon. However, I think that will be fixed with 8.1 later this month.
