Used swivels for years & gardiners new resi-neck ones are superb! There are too many benefits to list to be honest.
As has been said, you need to give it a little time to "click" but when it does you'll be flying!!

I like my tension set so that the brush swivels free/easily on the glass but just enough "nip" so that the brush doesn't flop to one side when you lift off the glass. I also like a little lube on the swivel joint & I find the gardiner ones better with the quick release lever on the bottom instead of on top as it comes, doesn't get in the way of the hose this way.
