Strength wise good aluminium lugnuts are strong enough indeed, it's not that easy to strip them. Cheap ones .. have no experience with them, also using rays duralumin lugnuts, for stock studs ones of
short type. But some buy them for bling/looks, and of course are not very happy to see lugnuts finish to be damaged.
Stock thread of studs/lugnuts should be M12x1.25. Most commonly used aftermarket studs, eg. APR ones usually have thread of M12x1.5. As i don't use spacers and don't remount wheels too often for stock to be soon to striping, not yet considering of aftermarket studs.
P.S.
I wouldn't overthink too much lugnut things. They don't cost extraorbitant prices, they don't change looks THAT much, weight gains with lighter ones are not too noticeable (even more so because stock nuts are rather light). Just get some you like look-wise from not cheap chinese ones to lessen quality issues chance and forget about it. Good aluminium nuts are not that weak. At most i would switch to some chromoly steel lugnuts, if car would see many remounts per year (such as to-from track day wheels), for some piece of mind. I wouldn't get some uber expensive ones too. Mostly it's about their bling, but if you remount, finish gets damaged .. so why pay too much for some uber-titanium burnt finish for it to be scratched later on. Rather get cheap set with some spares if some ever gets striped/got lost or damaged by lazy tire shop staff.
