Not sure why people are still asking for what it compares to, this pretty much sums everything up right here.
13 transformations in and still holds together like a champ and nothing broken. I mean really, at this point if you like it buy it, if you don't - well just hope we get another one within the next decade.
Also, as a side note, I think I have only seen one report of a breakage anywhere. I guess time will tell if anything explodes, but seems to be made right to me.
