Bubble Trainer vs SngWiz Quiz

[eMbAh]

I was wondering if there is any significant difference between the two? Which one is the best?

i think bubble trainer is best for a quick refresher, but nothing comes close to SNGwiz

That's good since i got the full version of sngwiz. Maybe this was a stupid question but since the sngicon people talk about bubble trainer i was just wondering because bigjoe said it was the best on the market in one of the videos. I thought ok, maybe it's more specific in some areas ect
