I've liked handmades since the first one I won in a marble game.
One of the big appeals (for me) is how remarkable some of the intricate balanced patterns are that got turned out by hand, with basic tools, and not "mass produced" by machine. Yes I know some of the glass huts DID crank them out in great numbers but that makes it even cooler that they could make so many with the technology available at that time.
As much as some machine-made fans claim to dislike "the name game", that's one of the topics that gets the most discussions on the board. Everybody likes controversy and let's face it, narrowing down which glass house made which handmade isn't nearly as interesting or controversial for some.
IMHO I think most "nice" machine-mades are more of a quirk than anything... but don't get me wrong I've seen plenty of really beautiful machine mades with cool patterns and colors that would be impossible to make by hand.
Different strokes for different folks... it's like comparing apples to oranges but as long as you like fruit, all's good.
