Levin is good in monologues. Very informative, clear and logical. As a host engaging in conversation - he is a bully, mostly incoherent.
Prager and Medved are the best in letting opponents hang themselves, politely but lethally.
Rush is excellent up to the point of going into his self-aggrandizing shtick. I can see how it can turn off an accidental listener who has not developed an appreciation of him yet. But hey, Rush is #1, so what do I know.
Both Levin and Beck claim to be #3, and I think that is the source of conflict.
To me, the more, the better. I appreciate all of them, as different as they are.
Excellent points. I totally agree with your critiques.
