Your average club player only encounters experts at tournaments, unless of course they play at one of the clubs on Vancouver Island, where you are likely to run into one of a handful of experts living in the area and to a limited extent, a the big games in Vancouver. At the average club games, where as you say, the vast majority wouldn't notice or be able to take advantage of any leaks.

How important is addressing this information leakage, given the memory load the complexities involved in these systems?
Is it best to attempt to play the best possible system or play a "lesser system, better"?

How about playing any system better?

Now, if you still think that the best way to invite in notrump is to use 2C even without a major, I’ll concede that puppet sometimes doesn’t leak quite as much information. But…at least amongst good players….you are significantly behind the times

The question was whether Puppet Stayman leaked more information than regular Stayman. I'll stick with my conclusion that regular Stayman leaks more information. As far as using 2♠ to ask for a max or showing clubs, that's an entirely different question, and one that is irrelevant to the original question since that can be used with with regular Stayman and Puppet Stayman. And as long as a non zero percentage of players don't play the 2♠ max/clubs response, my comment is accurate.

Still seems accurate even if they all do, since isn't range ask only when you're not interested in a 4-4 major fit? Puppet leaks more information when opener has a 5 card major, but less when responder has a 4 card major and choice of games hand, which is more common.
