I know they've made great strides but "Behringer" is a bigger indicator of quality than XLR or USB in that sentence. Blue at least has been making good mics for their entire existence (I use a Snowball too, it's great for my day to day calls). They've managed to stay pretty good since the Logitech acquisition, and prices have come down with scale.
I don't know. I don't exactly have a "radio voice" and my Behringer mics seem to work fine--together with a mixer that is way higher-end than the mics in general. Again, for most people, there's a huge leap from built into laptop to just about anything else.
