I have the Icon and use it for all sorts of dives as a tropical travel BCD to a cold water BCD with a drysuit. The later tends to put me into an extra weight belt and really pushes the back support to the point it feels a bit floppy. The former application required me to add a crotch strap.
The main differences I saw are trim weights, back support and nifty folding. Beyond that, I don't see 100 Euros worth of difference. Based on where you live, I don't gather you'll see much cold water diving where you'll see the benefits of the back support. Either way, I'm happy with my Icon and until I go doubles and need a new one, this will work for me.
