rF1 is regularly more crowded than rF2 online. AC isn't very league or online-ready at moment, so it seems to me the main competition for rF2 is still rF1 for leagues and random online sites as Race2Play. Daily peak counts have been a little above 100 from late 2013 onwards as far as I can remember. There was some development around a year ago, then slight dip, and now again last months slightly more activity with some new mods released. I agree. My league made the move to rF2 last year and it took a big commitment from me and some other admins to get the content and everything ready. It was something I would not do again with hindsight, but once done rF2 has been fairly good for us. The problem is the interest (less interest = less mods, less participation, less competitive), unless your league has very good resources and is very well established, it's hard for me to recommend rF2 over rF1.
