53/19 is marginally taller than 39/14 but I doubt if many people could detect the difference. The only thing I would look at is the difference in chain line. 53/19 might have a better line, so there would be less noise and friction. Still, it's pretty subtle.

If you can tell 0.135% difference! I don't think Lance would even fess up to that.
Wheel size really doesn't matter.
Speaking of additional insignificant thoughts, which has more friction? Smaller diameter "gears" that cause the chain to flex more, but use fewer teeth or....
I think soma5 pretty much hit it on the head with chain line differences.

Larger chainrings and cogs have slightly less friction than the same ratio with a smaller ring and cog, due as you mentioned, to less severe chain flex. However, as also noted, the differences are miniscule.
