I've been playing still on 1.5 and starting to feel the pressure to move up to 1.6 and update the mods I use for it. I've been meaning to just reinstall my Skyrim from scratch to 1.6 and start over with my mods, but fear from the recent changes making some essentials like the USKP not working, the Companions questline broken, and other worries.

So, is it advisable to move up to 1.6, or keep on 1.5?
