Gladiator comes with a learning curve to get the best out of it. The patches suck, all drowned in fizzy ghastly reveb and ping pong delays, very trancey. Unusuable garbage. Unless you drop more money on the extra patches they put out.
That said once you learn it well, it opens up better than any synth that I own. Very flexible, can get you most sounds.
Filter implementation ie. it's placement in the signal flow is not the best, so they have these drop down static filters that you can add to the waveform and morph the response during a cycle... it's ok, working that way, can be a limitation, but that limitation, to me, is what gives it is signature sound and drives your workflow.
I would not choose it over Omni/Sylenth anyday ever. Can't $300 get you a Diva? I'd go that direction!
