I dont think I can give this a fair comparison. But I own a Leopold and I was over at a buddies playing sc2 and we swapped keyboards for a few games, I love the feel of the leopold much much more. But like I said the reason I cant make a solid compairson is because his filco is 2.5 years old and has gone thru tons of wear and tear vs a brand spanking 1 week old Leopold. The difference is very noticeable and much much nicer sounding and feels more solid and nicer on the fingers and the sound was not as "cheap sounding" while gaming/typing. Even the filco owner noticed a pretty solid difference. Like I said tho the age/wear and tear difference I am sure makes a huge difference. So I cant give it a fair comparison.
Also the letters on the 1,5,A,S are completly worn off lol, which is typical of ANY terran SC2 player.
