sngs are typically softer than cash at lower stakes imo. my winrate is certainly better in sngs. i think they are more appealing to the average fish because they are more alike the style of competition people are used to (ie clear and distinct "winners", prizes etc). cash games are more of a grind, and the results appear more long-term. also, tournaments are probably the style of poker most people are used to from their home games/pub poker leagues (at least here in australia) that they sometimes win and turn their $5 into $30 in.
