Why are inverted forks better than conventional forks?

I was thinking about this on the train ride today. Why are inverted forks better than conventional forks? Ive been told time and time again they are better, but Ive never been told why, so if my someone asked me, Id have no answer. But Id like to know. Can anyone explain why inverts are better?

Someone told me it's because they put the heaviest part of the forks near the ground, and thus lowering the center of gravity of the bike. Don't know how true it is but it sounds plausible. Maybe it's just because they look cooler. lol

inverted forks have less flex than conventional under extreme conditions, normally not felt just street riding

inverted forks actually have the heavier part at the TOP. i heard it's because the fatter portion of the fork is held within the triple clams, which is a more rigid setup and provides less flex and better feel/control.

the heavier part moved up higher on the fork means less unsprung weight (the heavier part of the regular forks are "under" the suspension and act upon it more than just its own weight, more like an exponential amount of its weight). that allows lighter components to be used inside the forks as well as on other parts of the wheel...in general.

They increase front end feel and provide less flex.

All good theories, but don't forget less stiction as well. The combination of the heavier part being on top and gravity will keep things moving much more freely than conventional forks.

1. less flex due to larger diameter tubes located at the area of largest bending moment (near the triple clamps)
2. lower unsprung mass - though I've read that some standard fork setups actually have less unsprung mass, my experience has been that "upside-downs" generally have less

not sure I follow the stiction argument - seems that the overall bike weight would dominate?
