As Gardy said, not everyone is a competitive player. However, I may not be much of a Garbodor fan, but my thoughts on the Pokemon were changed quite a bit thanks to watching Marriland's Black Wedlocke where he had to shoehorn a Garbodor onto his team after losing his Carracosta on Route 10.
He was like not very happy about using a Pokemon he didn't like the design of, but come the final battles he does a very clever Rest + Stockpile strategy with said Garbodor, however he eventually gets cut short by a crit Head Charge from Ghetsis' Bouffalant, and Garbodor's partner (a Sawsbuck) eventually ends up sweeping the rest of Ghetsis' team, including OHKO'ing Hydreigon with a crit Jump Kick.
As for Lilligant, it's such a great design and while competitive isn't the best due to its shallow movepool, it does do surprisingly well in casual play, thanks to learning some strong attacks like Petal Dance and Energy Ball, as well as Leech Seed and Sleep Powder to debilitate the foe while setting up Quiver Dances.
