Best Server:I use Spigot for my server; is there something better w/ more capability?

I love Spigot a lot and I'm very happy with it. Just curious because I need to know if something out there is better. Spigot stays pretty up-tod-date and has plugins seamlessly, though they're limited on certain things w/o mods but people find ways around constraints all the time. Spigot is really hard to beat. What's your preferred server hosting software, what special features may they have, and do they stay up to date?
