What's the longest biologic (TNFi) you've been on/which has least side effect for you?

I am about to start a biologic but have difficulty choosing the one with least side effects. I've read plenty of studies but they're giving me no direction. Tocilizumab seemed like a good option until I read several things about it not putting certain side effects on the label and FDA are getting complaints from users that weren't warned about certain stuff.
