I too have had more bikes than you can shake a stick at (running list here:

The bike KarlC linked above, my Litespeed T3 has been able to survive the ever revolving door of bikes coming and going. Of all the bikes I've owned, it's in my opinion the best riding bike. Litespeed is very big on tube manipulation which I think helps define the ride characteristic where it's able to match the feel of a carbon bike while being compliant and smooth. I think Seven is the only other company I'd consider buying a Ti bike from. Moots is as prevalent in LA as a Tesla, and that'd bother me. I'm sure they're great but I don't like seeing 6 identical bikes to mine on a group ride.
Litespeed may not have the sex appeal of some of the other manufacturers but they've been in this game longer than anyone else and know how to make a damn good bike.
Lastly, fwiw, I ride a small frame so ymmv with a larger size but a medium (54) should be similar in ride.
