Oils are definitely better but I really don't believe the marketing in winter. At low temperatures even modern oil has high viscosity. Combined with tight bearing clearances I firmly believe in waiting a bit to be sure everything is nicely coated. Maybe I'm just paranoid from horror stories of dudes getting on their bikes and ragging them right off the bat, seizing the engine. I mentioned the aluminium mainly because piston slap came to mind. More slop, more slap. It's better than everything twisting though.
