Kobo Forma or Libra H20

Hi all,

I have a first generation Kobo aura H20 that I have used for a little over 5 years. It has served me well and honestly, it still works pretty great. Nonetheless, I was considering upgrading to a Forma or Libra. I'm curious to see which one people would suggest getting. I understand that the Libra just came out but still would like to know your thoughts.
