That's one reason I love my combined school - it takes the best from each style and makes something amazing. We really only use the karate to learn various ways of kicking and punching - where to hit for most impact, how to angle the fist/foot/hand, how to strike with multiple attackers. The boxing we do supplements it really well and makes a nice fusion. So we get the striking and kicking aspects with the throwing of judo and the grappling of jujitsu - best of all worlds, I reckon. :D
I've found it really great as a woman because it teaches me a lot about using bigger, heavier opponents' strength and weight against them, and about getting out of dire situations (though, of course, more importantly, not getting in them in the first place). Most people don't expect a girl to be able to hit properly, so that's nice. I'm not a small girl (5'10", 149 pounds), but most of the guys I train with are absolute bears, so it's good practice. :)
