I do not want to get too far down the line of being against the smaller ISPs as I get bashed for it, although you can imagine which providers typically have the most direct peering.
Ultimately it is your choice, my personal view is the Safe Bet is BT, it's a good mix of price and overall reputation. It's also one of the few offering 55Mbps.
What is stopping you getting Infinity 1, and seeing how it fairs for you? I had 76Mbps for years and dropped to 55 with BT, then down to 38 when I moved flats and I notice zero difference day-to-day, no regrets for me, nice saving. Once you go live on Infinity 1, pop up the stats from the HelpDesk page of the SmartHub, here we can give you an idea of what speeds Infinity 2 would typically yield.
Looking at the estimates, I would say 50Mbps is a nice estimate, in many respects lines are more stable when they have a slightly lower speed and hence a higher noise margin. E.g my line has a 16db noise margin, hence it really never drops. If I went to a 76Mbps package and the noise margin went down to 3db, I am sure there would be the occasional drop.
Here are a few of my tests from the BT days (all tests over WiFi):

Here is my Sky line, as you can see with the two lines being quite separate, it shows evidence of congestion, Certainly, it is nowhere near as nice and smooth as my BT used to be:

I still manage a bunch of streaming, some gaming when I get chance etc on the Sky line and it's my daily driver right now. The point is my line right now is not
perfect but day to day I don't really notice a real difference over my perfect 76Mbps line. Sometimes 4K struggles, but rarely, when it does it automatically falls back to 1080P and I don't really notice unless I check. I think overall you will be happy if you don't constantly run speedtests and look for faults, once you have it going you will just set it and forget it.
I think your prior fault with BT which was handled poorly is creating a lot of this anxiety. You were just unfortunate here, most of us have stable, solid lines.
Out of interest on your VM line can you run a speedtest here and post the results. The speedtest here gives a much better picture than the speedtest.net
