The leather is good because it was different, something Sentai designs have been starving for. Seriously, it's pretty much the same suit each year, just a new helmet and paintjob. I mean, it really says something that Kyoruger adding a shoulder pad or Gekiranger's lack of belts can be considered massive departures. I mean, you look at Kamen Rider for example, and you can see just how stunted Sentai designs are by their adherence to formula. Just look at the difference between, say, Gaim and Wizard and you can immediately see how massive a change there is, with Gaim's battle armor vs. Wizard's longcoat.
