The only place I've really noticed the Makita having more power than the Festool is cutting 3 sheets of 3/4" plywood at a time. I have zero experience using them on rough lumber but understand the TS75 does that better. It comes with a 75" rail in the price.
I personally wouldn't want a Dewalt. It uses a weird track that doesn't allow parallel guides, being squared with a big framing square, and only has 55" and 102" tracks available. Dewalt doesn't make it but buys it from another company. Stanley Black and Decker has a history of abandoning every single product that they have ever handled this way.
Joining tracks is better than nothing but a poor substitute for a longer track. Plan on having a long straight edge and being very careful if you have to move it to another sheet of plywood.
