There are six fully-evolved Grass-type Pokémon in the Sinnoh Dex and an additional 21 fully-evolved Grass-type Pokémon in the National Dex. Of the 27, there are a few with fantastic base stats that set them apart from the rest of the herd.
Shaymin
Shaymin's two forms have a total of 600 base stats, but Sky Forme swaps out some of her Defense and Special Defense to boost her Speed, Offense, and Special Attack. This makes it a hard-hitting, yet fragile Pokemon with STAB moves like Air Slash hitting harder than its Earth Form could. He learns this move if he is upgraded into his Sky Forme at level 64. Seed Flare and Leaf Storm are his strongest grass-type moves and are some of the strongest in the series.
tangrowth
With a base stat total of 535, Tangrowth is a mixed offense presence with mediocre Special Defense. It has high HP, Offense, Special Attack, and Defense, which makes it capable of tanking physical moves quite well. He has a bit more special attack, which makes moves like Sun Beam and Energy Ball better suited, but is also able to learn Power Whip and Seed Bomb. He can be made very powerful in the sun as he makes good use of Growth stat increases if he has both special and physical moves.

Skeptical
High Speed and Special Attack make Sceptile a powerful starter Pokemon, but its total of 530 base stats makes it one of the best Grass-type Pokemon overall. He can learn the Sword Dance to try and take advantage of his many physical moves that he is also capable of learning, such as Leaf Blade and Earthquake. His defensive stats aren't very high, but he can tank a special move very well and recover his HP with Drain Punch or Giga Drain.
Leafeon
While Leafeon isn't the most powerful Eeveelution, it can thrive under the right circumstances. He has a base stat total of 525 with very high defense and offense. His other stats are low by comparison, but if he increases his speed, perhaps through his hidden Chlorophyll ability, he'll be devastating to face. He can learn the Sword Dance to make the most of his already high attack stat while using powerful physical moves like Leaf Blade, Iron Tail, or X-Scissor. He doesn't have a choice of the best moves, but he does his job well enough as a powerful physical sweeper.
torterra
Trading its low Speed for high numbers in all other stats, Torterra is one of the best Grass-type Pokemon on any team. He has a total base stat of 520 with very high attack and defense. He is extremely weak to ice moves, but can deal with anything thrown in his way. Earthquake and Wood Hammer are his strongest STAB moves, with Stone Edge and Superpower being good coverage options. Curse is one of his best stat-boosting moves, but he can also use Swords Dance and Rock Polish to great success.
