I think the reference is to a seam (or not) that runs along the length of the tube.
I'd actually expect seamed tubes to be better (so long as heat wasn't being transferred through the seamed area). I'm reasoning that the shorter the distance heat has to travel through metal the better (like thinner baseplates in waterblocks being better).
I'd also expect that a limitation to making tubes thinner is their rigidity during manufacture - and a seamed tube had ought to be more rigid than a seamless one (either drawn or continuous weld - actually I don't know which process might be used for seamless in this case - and one could argue that continuous weld isn't actually seamless) so enabling use of a thinner tube in the case of seamed tube.
I'd also guess that the difference between brazing with copper and soldering (even with silver-content solder) would be a bigger deal than seamed/seamless.
But that's all guessing and what the he** do I know?
Interesting to hear that Bill's moved from Swiftech to Coolingworks. Sounds like a different set of challenges - hope it goes well
