Although looking at clubs like Besiktas, Galatasaray, Trabzonspor and Fenerbahce, you will understand that the four clubs is a shareholders as far as Turkish league is concerned, so I'm not that surprised to see that OP only mentioned these four clubs for people to vote on the club we think will lift up the Turkish cup in this season, i know that there will be a great competition within the clubs but i still vote for Galatasaray club to carry the cup because I'm have been a good supporter of Galatasaray club before now and I'm not equally bias, so if any clubs out side Galatasaray happened to lift the Turkish cup, i will not panic because i was celebrating who ever win the Turkish cup in this season.
The same teams have won for the past four years, and one of them will likely win this season as well. I’ve picked Galatasaray partly because I’m a fan, but also because I think they might have a slightly better chance than the other teams; still, given the nature of the cup format, surprises can happen. A favorite could get knocked out early anything is possible. To be honest, though, I’d like to see a team other than the Big Four win the cup.
