I guess it's possible they don't all start equally, and I have been fortunate to get two that has been exceptional. I would say the big blocks may start differently, and that is why I would like TLS to answer this question, he's had experience with both.
Even though the system is running in open loop on start up, its running on a pre-programmed map for a cold engine, ie replaces the choke. Also as GMLC suggests, the EFI system is much better than a carb/choke system working on venturi, the fuel pressure is primed and ready before the starter motor turns, unlike a carb engine which would need to draw the fuel/air mix in.

I really wish we had more EFI options available over here atm.
