As a Grass/Poison type, he actually has fewer weaknesses (4) than a Grass type (5). He also has STAB for both Grass moves (like Giga Drain) and Poison moves (like Sludge Bomb). I know he’s a tad slow, but his stats are pretty good overall (especially Special Defense and Special Attack).

Yes, I would say it is underated. Every stat category is above average in MY opinion. Its move pool was not the best, but Generation 4 added a variety of great moves to teach. Also, if it has a nature that benefits his Spec. Attack…even better.
Base Stats:
HP - 80Attack - 82Defense - 83Spec. Attack -100Spec. Defense - 100Speed - 80
Who can complain about that for a Grass type with Poison, too?
Note: I’d go with Charizard or Blastoise over Venusaur 7 days a week.
