Trust me on this; I've got 3 U/F AKMs (wicked looking as all get out and love the looks), and I once had an FNC S/Folder, Uzi folder carbine, and Sterling MK6 semi carbine with U/F stock...
But by far and away, IMHO; the Romy/EGerman S/Folder is THE BEST and EASIEST to operate, the hands-down winner in full-on mil-spec folding stocks.
Flick one lever with slight downward pressure and rock your wrist to the right as you hold the rifle pistol grip - gravity snaps it into folded/locked position on right - where you can still operate bolt, safety, and mag release.
Need to open it into extended position? One gentle push of lever and rock wrist to left; stock swings back and locks into extended position.
It can't get any easier to operate, try a FAL/FNC sidefolder, Sterling, Uzi. Those commies knew how to make something simple that works.
A simple para-cord warp brings comfort to the steel itself.
Don't waste you cash on anything but the original no-gunsmithing-required real-deal steel Romy S/Folder and you will be happy.
