I know that's what I thought aswel would make me stand out a little just can't dismiss the merida all ur help is helping though gonna make my decision by the weekend im sure of it lol
What test riding gave you done? What is your goal for riding the bike once you've got it?
It's unlikely any one is going to be worse than the other two, especially when two are from the same company, but as has been mentioned they theoretically are designed with slightly different purposes in mind and if your final riding is going to fit one of the bikes design goals better than the other two then that's the one to go for, especially if your test riding hasn't really emulated your final reason for having the bike, just in case issues start to show when you start using it in anger.
Or just buy the lime green one that wasn't on your list, it looks stunning :-)
