I flew the G200 once and I worked at a department that had them... they have really high ref speeds, they have boots instead of heated edges and eat up a lot of runway in a contaminated situation. If I had the choice of boots or heated leading edges over in Russia I'd probably shy away from the boots. It definitely didn't have the dispatch reliability of the standard Gulfstreams. Again, I'm not typed... the avionics were nice but it wasn't my favorite aircraft.
