Looking for the best market research tool for Amazon MX (Mexico)

Hey guys, I’m looking to start my own Amazon business in Mexico and I’m wondering what’s the best software available for this marketplace. I’ve used the trial versions of some of them like Viral Launch or Seller App but I found out they are either very inaccurate or have limited features for the MX marketplace. Is anyone here selling on the Mexican marketplace? What software are you currently using and why? I’m currently inclined to go for either H-10 or JS.
