I've tried the Cherry's and the Micro-Leaf.
On the Track and Field test, I seem to average slightly better scores with the Micro-Leaf (playing side by side to eliminate other variables). The Micro-Leaf are definately much quieter and have a softer feel (less resistance and push back). As to whether they are better, that is really up to you. If you are used to old school leaf switches, they will probably be the better choice. If your used to more modern games, stick to the Cherry's. I wouldn't let a few bucks stop you though. Think about the $$$ invested in other less important parts of cab.
I've just ordered some Versa-Micros. These sound interesting as I've recently been manually 'tuning' a couple of Cherry's to change the feel a bit myself. I'll let you know how I go with them.
