Reducing line twist is about the best benefit = hence keeps your lure from spinning in front of finicky fish.
The slower drop is sometimes a bit of a set back when you see school of fish below you, but if they're attacking your lure in about 15-20 ft of water - it's no worries.
In deep water - slower reel up of fish, generally means higher chance of release survival.
Most of all, it's just fun.
