The team of the German site Gotools TV performed an extensive comparative test of many corded tracksaws
(the corded TS55 and Mikwaukee were not included):
The clear winner is the TS60. It was known that it superseded the corded TS55. If I remember correctly (I watched the video yesterday), it was measured i.a. to cut at a depth of 66mm without guide rails. The TS75 was found not to be accurate enough. For the testers, the TS60 was found to also supersede the TS75 and globally clearly better than all saws in the test.
One saw to rule them all?...
