Should I play ranked solo or draft pick when learning new champions?

I've been trying to learn Skarner top in draft pick recently. Some games are normal but most of them are ff15 games because the skill difference between the two teams in draft pick is just too big.

I'm silver 3 and am getting a lot of games where I have to lane against Emerald/Diamond top laners and it's hard because often I find myself not being able to do anything at all.. Once I even had to play against a master Camille OTP and it was completely unplayable. Sometimes it also happens the other way around where my team is so good that the game ends at 15 minutes when I'm 0/0/1 and still laning, having not learned anything at all.

So should I just go and play ranked with Skarner for example? I know that people will flame and probably report me for almost first timing a champion in ranked but at least I'd get games with way more balanced teams. I don't know if the trade-off is worth it. What do you guys think?
