Dwarf Gouramis are Dwarf Gourmais, there's only one kind. The only difference is the colours if that's what you mean? In which case it's just up to what you think looks best.
Or are you getting them mixed up with Honey and Sparkling Gouramis? They're both very small too nut "Dwarf Gouramis". If you're looking for the best temprement with other fish then I can only tell you from personal experience and I'd go for Honeys. They have a very lovely nature and don't even seem to notice other fish.
I have Sparklers now and I suspect they're nipping people in the dark!
