Assuming both would use Edis type ignition what are the pros and cons of either system

Megasquir v2 is exactly the same as microsquirt main difference in that microsquirt doesn't have a MAP sensor built in and it can run twin spark plugs as it was originally made bikes The microsqurt. Also comes in a smaller watertight case apart from that no difference

Thanks I'll soon see which way to lean, Hunted high and low at Stoneleigh for Trigger Wheels but it seems they all had the trots and backed out
