It's all about what one owns and has either had problems with, or not.
I have the Aspire
pegasus (won it) and although I don't use it often, haven't had any problems with it.
Keep in mind that I don't use TC on any of my mods, strictly kanthal.
I have the Aspire Triton 2
tank and don't like it very much, although I like it much better than both the Lemo or Lemo2
tanks that I bought and hated them so much that I gave them away.
I also had an Istick that broke within one month of buying it.
So Eleaf is not one of my favorite brands.
I have had very good performance from all of my Innokin stuff, so they rate high with me.
It's kinda like Ford/Chevy, some people love one and hate the other.
