1. The simple fact that they managed to engineer a new transformation to approximate a look of the on-screen character. This is not simply a downsized toy, it was a newly engineered one, and Bandai of America really outdid themselves with it. 2. Everything locks in so solidly! You wouldn't have guessed from the weaker plastic and the rubbery connectors that the BoA Megazords use, but everything fits together so well on the Gigazord. No, you can't expect to give it a heavy shake and not have anything fall apart (I haven't tried it yet, though), but it's stable enough to be carried around easily, which I was very, very surprised with. 3. Nothing is left out of the combination! Every part is used, which is quite an impressive feat. Maybe I'm just more used to the Gokaiger-style mecha (which is the only other line I invested a bit more in) but I had not expected all the little pieces to find somewhere to go. Even if they didn't, the nature of Zordbuilder allows you to find somewhere to put parts, anyway. 4. Ultimately, it's just oodles of fun. The transformation is very interesting and the toy, while not having the fancy motorized gimmicks of the original, still has nifty features like the manual rotating cannon. Each auxiliary has a little gimmick in place, and the base design already gives you tons of combinations to play with. What's more, with Zordbuilder, there are even more combinations to mess around with, your imagination is the limit!
