so u guys cant decide either which one would be the best for me ? 
about brown: i read they are the worst for gaming.. also the diagramm of them looks totally different.
They're certainly not the worst for gaming, they're a great gaming switch as well. Browns are a very safe first switch, they're good for gaming, good for typing, and very popular so they're easy to resell if you somehow don't like them. If you bottom out the keys while typing, they're a bit louder than a rubber dome, I find it's a very satisfying sound without being overly loud or annoying.
As for the diagram, browns have the activate and release point in nearly the same spot, the same as with a black. The two differences are browns have a slight "bump" in them, the tactile point, and browns are lighter, easier to press a key. I find blacks very tiring to type on for any length of time, and I love the tactile point on browns, it's just enough to keep me from accidentally pressing a key while I rest my finger on it, without making it overly hard to press.
As for blues, they're a great switch to type on, and honestly not bad for gaming either. The chart looks different than browns because the release point is higher up than the activation point. A small amount of people have a problem with this, but it's overhyped, most people have no issues. If it was a big deal, Razer wouldn't have released their "gaming" mechanical, the black widow, with only blues. I like the click of blues, but it can be a bit much for other people if you type fairly fast.
If you plan to do a decent amount of typing, get something with blues or browns. Browns are the safer choice, like I mentioned above, but don't be afraid to try out blues if you think you'd like them. I find even the "worst" cherry mx switches MILES ahead of any rubber dome for gaming.
