Remember, this is entirely based on my opinion. You can criticize me mercilessly if you wish.
BTW I don't like quotes, but it is hard to keep context with so much repeatative misunderstanding flying about.
I think people assume that Asmodian Scout is better than Elyos Scout, or vice versa, which is where people say that Asmodian or Elyos have clearly better DP, on a basis of 2/1. This is simply a matter of context and perception. Firstly, we can only play on wording unless someone has tested the DPs. Secondly, the word increase and 100% clearly explain that your capability in such doubles. What is 100% increase of 2? These contextual basis of power, mean that it could be a meaningless double of an ineffective property, or it could mean a very high rate for an already effective or high property.
Your basically weighing what is clearly physical invincibility, against really high overall defense. Without context as too how valuable 100 magic resistance increase is, or how effective those increased by percent values are, there is no clear cut winner.
And since they have started to change them around, and many of them are horribly overdone or even underdone, it is pretty obvious that these are abilities showcased outside of their typical aquisition level, and that there will be scaling power of a relative, and hopefully fair nature. I would just let this rest til we have more information.
