We've got Ubiquity and Ive had a little bit of experience with Ruckus at a school I worked at. Personally I feel Ubiquity is a set and forget process (bar the odd update) works flawlessly never had an issue.
Regarding the Ubiquiti, I am really happy with my home setup with several Unifi components, but sometimes, it feels that new firmwares are not well tested before they are being released. But still, I am really huge fan of Unifi and, for home setups, and for my knowledge level, I found them to be great.
Ruckus/commscope has a greater depth of RF products, so in tough situations you potentially will obtain better coverage with the Ruckus gear. It comes at a higher cost though, fewer sales channels, and less community involvement. Unless you really need to address a weird situation, Ubiquiti is a solid and less expenisve choice with nearly all the usual enterprise features.
