They are both the same...ish. Keep in mind that damage that is allegedly caused by cold starts is caused by lack of lube for the first half second. If you start a cold engine and shut it off right away, there will be plenty of lube there for your bump start after EOCing. I have seen engines run for 10 minutes without oil in them. Half a second during cold startup is nothing.
I really don't buy the talk that cold starts is a huge wear issue. This seems to be a myth propagated by synthetic oil companies a few years back, aka.."use our amazing oil to avoid cold start damage." When most engines last >300K miles these days, who really cares about cold start damage anyway?
