The third tank seems to have been done by someone with a grasp for asian/natural styles, but there is a definite sense of incompletion in composition . . . The foreground area is too thin, the crypts behind them are too thin, the micranthemoides and hornwort are weak and thin compared to the over-power moss/wort, crypts, and ferns . . . Without any hardscape visible, there is a definite sense of a lack of structure. Basically, I feel it to be very lacking.
I'm not even going to talk about the cichlid tank because the composition there is just plain weak.
As for your tank . . . well, you got to admit that those sag's are way to strong dude. I'd break 'em up. Having such tall sag's wouldn't be a problem if they were spread in a foreground of open space mixed with some stones. The background is wonderful, if not a bit too full. An interesting midground would help give the tank more depth.
Overall though, I'd have to say your tank is the definitely the strongest dude.
