Not only that, IMO, comparing any two bonsai for any reason whatsoever makes no sense. You look at what is in front of you without any baggage. If it moves you - good, and if it doesn't - move on.
But back to the original query, I suspect that the smaller the tree the more your imagination needs to come into play and I also suspect that those who like huge bonsai only are the kind of people who would rather have a story read to them than be a part of it. (if that makes sense) We just had our annul show and best in show was awarded to a huge tree - again. There where any number of better trees at one eighth the size. When I say better, I mean with more considered branch placement, finer rather than rough, more thoughtful compositions etc. But no, the big one got it. So then, even for an experienced observer, the impact of the big won him over. So there are two ways of viewing, the layman's (general public) way which does not seem to be reserved exclusively for the layman, and the deeper observation that uses your mind as well as the image in front of you to make a ''story''.
In simpler words, It's easier to look at large trees.
