They're a business, I don't see how like/dislike is particularly relevant. I will go with whoever provides the best service and is not too expensive.
While I really want to move to CityFibre for symmetrical, I strongly suspect Openreach are a more robust network. Also less prone to failure as their active equipment is back in a protected environment (an exchange) hopefully with a generator back-up, vs alt-nets that are using cabinets out in the elements, at risk of vandalism and car crashes and with at best a few hours battery backup.
I'd trust Openreach to fix a fault a lot quicker than anyone else, despite the problems I've had myself with them.
Line got disconnected from the cabinet due an engineer mistake and they left me all weekend without service.
Tags got stuck on the database when I tried to move back to Openreach service from Digital Region.
No business is flawless and if you're stuck on grotty old copper service subject to neighbours turning on their christmas lights knocking out your broadband, there's not a lot you can do. That is not a problem Openreach can fix, banding is the only solution to keep a service working when there is a problem which may be well outside of their control, its them doing their job by prioritising keeping you online.
