When I used to do Theatre carpentry, I regularly used Festool equipment (that wasn't mine). It was an education in how careful thought to your product design can make something much better to use. I have an Evolution Sliding Chopsaw at home. It cost £200 and it's great. The Festool Kapex is just better in a lot of small ways - the mechanism for adjusting angle is quick and precise, the laser lines mark out kerf width accurately, the airflow has been designed so that dust extraction works well etc.. It's 10 times the price though, so obviously not worth it for me at home.
If it's the best of the best the average homeowner shouldn't own it. (It's not a good value for them)
My beef with TOH is now that all the houses are so expensive and the work is so custom or complicated that it is not relatable.
Some of their stuff is nearly indispensable in a high volume or time constrained shop, though. The domino's only real competition comes from mafell, and it's similarly priced. Triton and some others have tried to compete with some dowel joiners, but they don't work nearly as well.
