the imposcar2 sounds pretty good, but the file management and overal ease of use is a little convoluted. I recommend sylenth or element. Both have great CPU management, and a really nicely designed UI and not too pricey.
Do you really want a synth with presets called: jumbo? it's nice and all... but it sounds like Jumbo. That's UW's thing... what's YOUR thing.
