You can't prefer a player for his style...really? YOu can prefer a player because of his hair style or, if you're that way inclined, the size of their junk, or their tattoos.
I don't dislike him because of his style, but his ability. Regardless of style a player can be selfish or not, can work hard defensively or not, can pass well, finish well, cross well or not. On top of that even not great players can be consistent in what they do, Schurrle both doesn't show a lot of talent while also not being consistent.
There are guys who play a very similar style, very pacey but are effective in lets say 7 or 8 out of every 10 games and throughout a game will be dangerous and good for most of the game. Schurrle isn't that guy, he had 4-5 games he actually effected the result in last year and all but one of them were against crap teams or Arsenal having their nightmare game(where they were genuinely horrendous). He's good in 1 or 2 out of every 10 games and in and out of most games. Plenty of players are mostly about pace but are still muccchhhhh better than Schurrle.
Either way, you can be poor and effective, brilliant but inconsistent, for me Schurrle is both not great, not very effective and not consistent. A "good" player for me would be either talented, consistent or effective(though ok consistent/effective aren't that dissimilar in this context). If you're going to be highly limited in how you play you need to be very consistent and work hard, neither of which I would regard Schurrle as, hence poor.
