I've seen him score a few good goals for us, so maybe that swayed me, he scored 5 in 20 at Derby, so that's a decent record for a winger, albeit at a lower level. As I said, he hasn't played that much and has come off the bench abit, he just looks more composed when shooting.
Also, I was comparing Ibe to Sterling, when Sterling is in a good shooting position you don't think goal, you think he'll panic or miss, for the amount of good positions Sterling gets into his return is poor.
I would also say that Sterling played in a much better team when we were tearing teams apart going for the league, so he looked much better, on his own in a struggling team he is far less effective.
I'd agree that Ibe looks like he has more power and control when shooting but the rest of his game isn't up to scratch, last season proved that. I also think your point about Sterling's finishing is correct, he's better when he doesn't have time to think and just shoots.
I think there is pretty much a year difference between them age wise, Sterling being 21 and Ibe being 20. Both are still very young and have the potential to improve but if you look at them both as of today and what they have done in football so far, Sterling is clearly the better player, his attitude may cost him in the long run though.
