I'm not a Ubuntu user anymore, but I still want to give my opinion: I hate staying behind on updates. I'd rather have it break a few days after release than postpone the trouble and wait until EOL. But that's just me. From my experience, the Ubuntu update process goes smoothly.

Take a glance at the changes[1] and see what you want to do. Either way, I'd recommend not postponing until EOL. I'd just recommend to wait a few weeks in order for the developers to iron out some of the bugs that usually come out on the first few days, and you're good to go.
