;They both have their uses; I have both, and multiple sets. I have some that are 20 years old that are just a standard looking socket, but have the rubber retention in the bottom. They have their uses....Work well on pretty much any car that is easy to get at the plugs. I also have the swivel type, which I used on my Wrangler when Jeep thought it was a good idea to make the owner not only climb their vehicle, but climb into the engine compartment to get to the rear plugs.....The best part about the old style is they are a dime a dozen. I bought mine at an auction for 10 bucks or so for a pair. The new style with the swivel I purchased off of the truck...not so cheap. But again, they both have uses in their own right, and eventually, you'll probably find it's easier to have a set of each.
