So... what is meant by "great"?
Good question! Of course, individual interpretations of 'great' will vary according one's own taste.
For me it is an aquascape that is appealing on many levels i.e. composition, pleasing textures, colours, hardscape selection (if used), fish choice, viability, sustainability, creativity, innovation etc.
So a great aquascaper is one that demonstrates the highest levels of the above criteria in their aquascapes. The greatest demonstrate these qualities at the highest levels, time and again. Amano is the obvious, for me. Others off the top of my head, in no particular order - Sabat, Senske, Navarro, Chong, Cheng, Lo, Chow, Deki, Law, Hui, Lazaveric (one to watch out for), Shiga. There are plenty more, and plenty more developing into great aquascapers as we speak.
And our very own Tom Messenger, Graeme Edwards, Dan Crawford and Peter Kirwan (zig) I would consider have produced great aquascapes - and will no doubt continue to do so. For instance - check out Graeme's latest thread about setting up a tank for Unipac. For an instant aquascape - that's pretty great!
And in the context of the OP - all of the PFK Great Planted Tanks featured so far are quite unique and do not follow this 'Bonsai-esque' style that you mention. All of them have innovations and this combined with their aesthetic appeal, for me, makes them inspirational and great for the PFK readers.
