Soldier Blade is a decent game but doesn't hold a candle to Blazing Lazers, Gate Of Thunder, Lords Of Thunder, or Air Zonk. However, I'm not sure why Dragon's Curse is even on this list...the rest of the games on this list bury it about fifty feet under solid rock in just about every way.
nat's right though...this one's not easy. For me though, I have to look at each game from a technical point of view and decide based on that. Having said that, I have to cast my vote for Lords Of Thunder. In terms of playability, appearance, audio experience, and overall presentation, it's the highest quality game on this list, with Gate Of Thunder taking a very close second.
