Best environmental analysis plugin to learn

Hi, I recently decided to learn as much as I can about environmental analysis, and apply those to my designs. I don't have much experience regarding this, which is why I don't know which Grasshopper plugin (Ladybug + Honeybee, DIVA or Geco) would be better to learn (If I'm about to absorb a whole lot of information on a small period of time, it might as well be the right one).

However, I know it might not come down to which one is the best one, but which one performs better in certain aspects, which one has the most tools, which one is easier to learn for the not-so-experienced, and so on.

If anyone can point me into the right direction, or contribute to any comparison information, it'll be much appreciated.

Regards,
