Your biggest problem is avoiding being sucked in by Festool hype, unless dust extraction is the most important thing on your wish list then a Bosch/Mafell/Makita or Dewalt will all deliver, and don't forget the Festool is the lowest powered of the bunch.
I feel like you've got a bit of an axe to grind here as I've seen you speaking up against the "festool hype" a few times on this forum.
Which saws do you have hands on experience with? Dust extraction is only one of many differences we're looking at here. I'll try to be fair because my Makita tracksaw had issues with scorching that I've not heard from anyone else, but there's a fair few ergonomic differences between the festool and Makita that I've found since switching to a TS55. I can't speak for DeWalt, Bosch or any others because I have no experience with them.
Better on Makita:
1. Anti tip feature is helpful
2. Preset 22.5 degree chamfer is occasionally useful
3. Scoring cut feature is nice, saves a few seconds compared to changing the depth of cut twice for every cut in mfc.
4. More powerful motor (although I've yet to find anything the festool hasn't cut easily)
Better on Festool:
1. The way it snugs to the guide rail is far superior (the cams act on a plastic strip, so you've got a wider contact area against the rail),
2. Depth of cut adjustment is better - dual scale saves the need for any mental msths. Also a fine adjuster dial, useful for non through cuts.
3. Better dust collection (very important if you value your lungs)
4. Detachable power cable (debatable usefulness but I love it personally)
5. Quieter, probably due to the less powerful motor, but it's important when you have neighbours!
Personally I just enjoy using the festool more, it suits my hand and has an overall more premium feel, which you'd expect for the higher price. The Makita has a more rugged workmanlike feel, I'd certainly feel happier taking that to a building site for "rough" work, whereas the festool feels more like it belongs in a workshop.
Overall I'm glad I made the switch, I miss a few details from the Makita but overall I'd say the benefits of the festool outweigh that. It's not just about "festool hype" - anyone who's used a few of their tools will tell you they're expensive for good reason. I used to be one of those guys who said "I'll never buy festool, it's overpriced and cheaper tools do the same job!" - the domino was my gateway because it's a unique tool, and once you feel one of their tools in the hand and use it for a few hours you understand quite quickly where that extra money has gone.
