All these bikes are great bikes. Choosing for a new project is not easy , but that's part of the fun
Sometimes I've learnt a lot doing this exercise.
If it helps you, what I do in my case is to give more importance to a sum of factors like the brand I'm a fan of, for whatever reason , (Pinarello is mine), a particular rider or team, ...than just THE FRAME.
In summary, I like bikes I'm proud riding on a Sunday and not because they ride well, or are particularly light, or ... So when I'm riding my (heavy) Montello , I feel like Perico Delgano winning the Tour , or like Ulrich with my Pinarello Paris...
Of course if you are a big collector and have plenty of money, that's another story, but that works for me as I have limited budget and space.
What I wanted to say is that early trek oclv frames are iconic and very nice, but as said, mainly because of HIM, I thing there are other iconic bikes I'd choose first and a Colnago C40 (or a Master... ) will be one of them. Are you more towards italian brands, french, british, ... bikes ? that can also help you to choose.
