For Bass, I like a 1/0 wide gap finesse hook...that's with a standard 5" stick worm like a Senko. I like Gamakatsu hooks but all the major manufacturers have versions. Also, every plastics manufacturer has a version of the stick worm. Lately, I'm partial to MaxScent Generals.
O ring or skin hooked, I haven't noticed a big difference in hooking percentage...although the O ring method tends to save on baits.
I also like to fish wacky style worms on the drop shot...not only for Bass but Walleye inhale them too.
Since Gary Yamamoto invented/developed the Senko in the early 90's, soft plastic stick worms fished wacky style have probably hooked more Bass than all other presentations combined. Even beginners can easily catch fish...it's what I started my kids with, and now my grandkids.
And...a bubble gum pink worm hooked wacky under a float will trigger Steelhead, especially after they've seen roe (or imitations) float by all day...
