I've used several brands and most work fine. I like the Berkley worms for their texture and toughness. I got some no-name worms cheap last year at the sportsman's show and have been using them all year with good results. For a good deal, Walmart sells Renegade worms dirt cheap. I haven't seen them in the classic bubblegum pink but I've used their purple ones and black ones to catch fish. They come in a big bag (maybe 20 worms?) for something like $1.49.
