i've been promoting TS in my rural community for 2 years. I'm yet to receive install myself due to remoteness and wayleave delays, but neighbours who have it are pleased.
Points to note-
1) feedback about low penetration wifi signal is only relevant to previous router. Current supplied router is mean to have good wifi signal. Of course, if you have existing wifi network, mesh or otherwise, you can retain that and ask TS to disable wifi on their router.
2) Their helpdesk appears to be Mon-Fri 9-5, so if service goes south outside thouse hours you'll be waiting until next business day for a response.
3) Bar the occasional glitch it really is 200Mb both ways.
4) If you want static IP you have to buy a business package - they don't supply this on the consumer £47/month service.
5) router interface is tied down, so config changes are done by TS via their Service Desk. They're happy to make changes, just don't allow user access.
6) take with a pinch of salt any install date unless your property has already been passed by their network.
I've been told I'll be connected in 1Q20, so will be able to give real feedback from then on.
