I've got the Bosch- imported it from the UK a couple of years ago. I also had a chance to try the Mafell. I didn't notice any difference in cutting power- the Mafell has some neat bolt-on upgrades, like the hinged blade housing and the tilt mechanism. But, overall, I didn't walk away thinking I should have paid more than double for the MT55. The Bosch definitely out-powers the TS55 and I also think it approaches the cutting performance of my old TS75, that could be due to the thinner kerf blades though. When I made the decision to get it, my TS55 was bogging down on some cuts that I thought it shouldn't and the TS75 was just too durn big. The Bosch has proven to split that difference admirably. The rails are an improvement in most respects, except for the fact that you cannot really use the MFT dog approach to rail setting because the saw overhangs the rails and bumps the dogs. So, unless you have a cutting table that is significantly wider than the piece you are cutting, it is a problem. I also miss the ability to clamp aftermarket ripping guides to the rail...there is probably a way to do it by attaching it under the rail, but I haven't taken the time to figure it out. Honestly, I am hoping that once these rails get in wider use, some of the geniuses who have been coming up with aftermarket products will put their mind to the Bosch/Mafell rails. I do have the right angle thing, and it works pretty well. Quite accurate at 90 degrees.
