Swap YZ 250 for KTM?

I'm currently riding an 00 YZ 250 and have been thinking about going to a KTM. I just bought my son a little 02 LC 50 SR. and for such a little bike the attention to detail is impressive. I ride mostly woods but also have a 1/2 mile moto style track on our side yard. I went to the YZ from a KDX 200. Big difference. I love the low end but even after putting a 11oz flywheel weight on this thing still has such a strong and quick response it's taking a bit getting used to (last off the bike episode resulted in 2 broken ribs, broke shoulder, and collapsed lung). I sure anyone reading this post is thinking "if you can't handle the power buy an XR 250!. My friends say buy a KTM E/MXC 250/300. It will be way smoother than your YZ with the same power. Never ridden a KTM 250/300. Are they that much smoother (a la KDX 200/220) than a YZ 250.?
