In my experience I’ve only had one new Ti frame which is an enigma esprit (still use it, purchased 12/13 years ago?!) Far East manufactured and still looking & riding well.
Also had a Sabbath Silk Road (sold) and the gazelle which were purchased used for about 1/4 of their new price. If looked after they stay looking almost new.
To keep them looking nice a dull polished finish is easier for upkeep rather than bead blasted, but it depends on how you use them/look after them.
The Enigma is a lovely soft ride, the gazelle frame is a little smaller and feels quite a bit stiffer, but both have their own personality.
Torus are another Ti frame company located near to me (Shropshire U.K.) and have tie ins with Burls, but their bikes are always built to a high standard with good reviews.
Good luck in your search 👍
