I'll add my two cents here. I hope I'm not being redundant.
I own the Realforce with variable key weighting and the EK 45g uniform. And I have the 55g version ordered.
First I only had the variable one. And playing games was awful, but typing was amazing! I play starcraft and I would have to switch to my Filco to play. But as soon as I was done playing, I would type on the Filco and immediately yearn for the typing experience of the realforce.
Problems with the variable weighting? Only for gaming, but when touch typing, it's difficult to notice the different weights. Granted the difference is obvious when you use the same finger or if you're typing and actively "listening with your fingers" for the difference. It doesn't jump out at you as you type. The only other thing is if you rest your fingers on the home row and look away for a while, you might find a line of "ddddddddddddddddd's" or "aaaaaaaaaaa"s when you look back.
Then EK had a "sale" with the EK 45g uniform selling for 200 instead of 225 so that was a good enough reason to buy it. Well that's the keyboard that I'm typing on right now. Thought it doesn't have that extra special little feel of the variable weight, it's at least 99% as enjoyable to type on. But I can play starcraft with it no problem.
I still like cherry switches better for gaming because I like the way they bottom out compared to Topre; When you bottom out on a cherry switch, it's hard plastic on hard plastic, very firm. Bottom out on a topre switch and you'll see that it's not quite as firm. Also I like the crisp very defined tactile bump on the cherry blues for starcraft; when I wear headphones and can't hear the keyboard, I find that disorienting. Not a problem with cherry blues, these f*ckers are loud.dddddddddddddddddddddddddddd <-- that's an actual line of "d"s that happened for real, Ima leave it there. I scratched my head and looked at something on my desk while I was thinking of what to write next. It happens, especially when coding because you write a bit and think if it's going to work, and what's the next step.
Well, now I'm getting the realforce 55g uniform, because keyboards. It's in the mail.
Since I started playing starcraft with my realforce 45g, I've really started to like how snappy the keys are. They are not very snappy but I like the way that they snap. So if they could snap that way but more, I'd be in paradise. So I'm looking forward to seeing how it's going to be. I'm sure the typing experience will be great also.
Final words on the different weighting of realforce keyboards:
Typing
-The realforce variable gives a magical typing experience through smoothness. The light keys are in no way snappy, which at first made me feel disapointed because it didn't feel expensive and I was used to paying for crispness and snappyness. But it became my favorite keyboard to type on very quickly (it's competition was HHKB, Model M, Cherry brown, Cherry blue, so that's no mean feat!). But gaming is totally awful.
-The realforce 45g gives a wonderful typing experience through snappyness rather that smoothness (not saying it isn't smooth, that's just not what makes THIS typing experience special). The uniform weighting makes it good for gaming. Not exactly as good as cherry blue for me, but only by a hair.
The difference for gaming is not enough to make me get up and change keyboards (for the cherry blue keyboard), whereas the difference it typing is (in favor of the realforce).
Your preference between smoothness and snappyness. As I said I was a snappyness man myself before I got the variable realforce. What made me get it is that I wanted a realforce but already had an HHKB (which is uniform 45g) so I thought about it and decided to buy the variable weight one. So even if you read my comparison and you say "I'm a snappyness man so I won't get the variable one", well that's what I would have said had I read this post before I got mine. I wouldn't say that now. Not at all!
