I disagree. Particular geometries will require the rider to interact with the bike differently; maybe where your weight is centered on the frame (bars in/down, for example) or how much steering input is required as opposed to weight shifting.

Intended purpose is another factor, too: the bike you use for crit racing need not fit like the bike you use for TTs, randos, or commuting across town.

I suppose it comes down to how different the frames are and how demanding the rider is, but even Hogg set up the article on the example of two identical bikes, so jumping to diverse frame geometries doesn't necessarily follow in that sense, either.

Anyway, the OP has already realized that same size bikes "can be totally different," so I don't think you're going to convince either of us otherwise.
