Interesting. I quite like Festool gear but I almost always buy it pristine, second hand from tool collectors on an upgrade path. The domino is very good as is the multi tool - way better than Fein for some reason, even though I think Fein make the Festool product.
For track saws I much prefer my Mafell to Festool.
For my use the 12" Bosch chop/mitre saw is more useful than the smaller Kapex as a chop/mitre saw. But I want to cut mitres in 4" oak.
I don't find the Festool routers any better than Trend.
Not tried the one handed planer yet, but I've got one coming from eBay for peanuts as I am soon doing another oak building and this is a quick way of whipping off the snaggy splinters on corners (which catch and rip sander belts)
The Festool work light and heavy duty tripod is a really good bit of kit. I actually bought that new for once, using a Voucher and FFX special deal which a member here posted about =D> I found that amazing for decorating and finishing work. However, in my current kitchen build I am presently using massive LED photography panels. Hollywood here we come.
I think any of the branded drill and driver systems are much of a muchness. I have Milwaukee drill and both their standard and oil drivers. They have taken a lot of heavy work driving stuff like 8" timber fix bolts into hard oak , but I think Festool or Makita would too. I don't think drivers are really a Festool specialism?
Much prefer Mirka sanders to Festool similar but bulkier offerings. Not had any reliability issues with mine.
For belt sanders of a heavy duty nature, Makita is my weapon of choice.
Festool vacs are pricy but very good. I bought mine as new, but second hand and would not part with it. Lidl vacs are also good and dirt cheap.
The Festool worktable system though is crazy expensive.
For big circular saws I like Hilti. Very tough and reliable. If I could justify the 12" Makita or could get my hands on a 16" Grizzly at sensible money, I would.
De Walt is my nailer system. I find it pretty good. Got fed up with gas nailer.
Looking at the above list makes me realise I have zero brand loyalty at all
I know people like to have a single battery system or whatever, but I don't really care. I have a place where I charge all my stuff up but if I was working out of a van it would be different. I also use 110v and 240v. It's no bother in a workshop environment.
