You're forgetting one big one in burgerland: Midway Games. They were owned and operated in the US, so they had a couple of advantages over the competitions. The first way that they had a much easier time negotiating distribution and marketing channels, so their arcade games were way, way easier for smaller arcades to order. The second was that they had a much better grasp on what Americans were interested in playing. That lead to Midway having four of the top 10 highest-grossing arcade games ever in the states (two of them were Mortal Kombat 1 and 2).
I can't speak for other countries, but Mortal Kombat mostly eclipsed the SNK fighters in the west. NeoGeo machines were common enough that there absolutely were people who played them, but people generally gravitated toward either MK or Street Fighter.
