Yes, I had the active order when I was originally moved to TTB on VDSL and also lost the backhaul listing off the portal later.
I seem to recall the latency was higher on TTB than BTW, though its all a bit hard to tell given there can be a 10ms delta between one PPP session and another, something which is somewhat annoying to be honest. Although moving to FTTP has shaved 10ms off what I had before, which is why I was wondering if I was back on BTW as I didn't expect quite that much improvement.
After so many people saying it didn't make THAT much difference moving to FTTP, its a night/day difference for me. Pages are loading much much quicker, some feel almost as quick as off my NAS, its somewhat surreal to be honest as I'd gotten used a few seconds stall between page loads.
Its especially notable sending files over my XMPP proxy to a friend in Texas. Large file transfers would often fail and I'd see the the data transfer constantly stalling, tested a file earlier and the speed was very consistent, not stalling and a much larger file than usually works.
I expected to be a bit underwhelmed after 5G, but this is completely another level.
