>>54711281I think its not so much a case of liking Grass especially as a concept (I like it fine, but not any more than say Rock or Poison as an archetype), but it just so happens that a lot of my favourite pokemon fall under the Grass umbrella. Torterra, Vileplume, Tropius, Trevenant, pretty much all the Hoenn Grass types, are some of my favourite designs and I often have fond memories of them from gameplay too.
Plus, I also like having access to status effects and debuffs in games, which Grass has a pretty good pool of.
