Yeah but usually stay in for several months and you have a discount if you want to buy them (though usually there are better offers online).
I agree they're addressing the same idea, but PS+ is probably the poorest one around, if you consider price versus what you get once you sub to it.
Thing is, they're not good services if you're looking for that one game to play for 500 hours, but they are good to play games in rotation as they come out, and have an "instant library" kind of thing, which is were PS+ fails the most at (though on PS5 you do have that thing, i'm not sure how it works out).
