Personally, I prefer stripper clips. Definitely quicker for me to reload using clips instead of magazines, so far as the SKS v. AKM platform is concerned. Maybe it's practice or maybe that reloading doesn't involve having to drop an empty magazine first.
I'll have to let you know about clips vs mags for me. I picked up my first AKM platform rifle last month. Still waiting to get out and choot it. Yes, it was a pre-election, covering my *** purchase. But that was my excuse for finally pulling the trigger.
