Guys,
Listen to what Ed is saying. He is one
very good bass angler. Even though he did win that day by a long shot with swimbait vs grub LOL, they are different plastics. Most grubs are fished bumping them along the bottom. Most of the time swimbaits are fished further up in the water column from just below the surface downward. Thats not to say you can't work a swimbait along the bottom, just most of the time they are swam if that makes any sense. If the fish are feeding at or near the bottom, grubs or similar plastics can work pretty good. If the fish are further up in the water column, other baits which are used in that depth will probably work better.
Also, keep in mind what species you are targeting. If you looking for halibut or bass, you may want to stay or at least start with bottom plastics. If you not getting bit, grab the swimbait rod and move up in the water column and see who is home. If the middle depths get you bit, then mix in spinners and cranks and see what happens. It's all good as the saying goes
