I used a single stage (RCBS JR3) for years. A couple a years ago I added a Lyman T-Mag II turret press to my inventory.

I find the turret press is very convenient, having all the needed dies mounted & ready to use. It's real handy to be able to switch back & forth between dies when you're working.

Time saved is minimal, IMO, when loading normally/sequentially. But when you have to re-doing some loads, or experimenting, it saves time exchanging dies. If you can justify (the price of) adding a new press it's worth it, for me.

(I personally don't have a need for a progressive, though I reload 200-300 rounds a week, usually, plus I do a lot of experimenting with new bullets/powders in small batches.)
