I'm enjoying being a manager. My team is pretty small, though, only 3, sometimes 4 other people. I still do a lot of programming, but I'm also mentoring--which I find very rewarding--and I have a meaningful voice in some decision making. Also, my boss trusts me, and encourages me to use his authority on occasion, too (a plan I've come to calling "weaponizing the org chart"). I don't think I could do that if I was "just" a senior developer.
