I was wondering the same thing about the Makita tracks, but I have seen two version of the Makita tracks and one has an extra lip on it. I'll have to check it out next time I'm at the tool store.
The Mafell MT55 can run on festool track or Mafell/Bosch, but that is the only one that goes "both ways" that I know of.
If you need a 3" cut then it s TS75 on FT tracks, or a larger Mafell saw on Bosch/Mafell tracks.
So if you are invested in tracks or not then one makes their choices. The Bosch tracks are nice.
