In a real world test there would be no noticeable performance
advantages or disadvantages because of differences in the shapes of
pontoons on pontoon boats. Find the one that is the size you want,
with the features you want, at the price you want to pay and forget
about what shape it's pontoons are. If you care about performance you
need to stop looking at pontoon boats.

That's sort of what I was thinking. and by meaning "performance" I
wasn't talking about stuff like speed and handling, but rather
operational economy. I thought it was odd that there that many
varient's in tube designs, though.
