Well Idk if its better or worse but mine looks like I'm watching it on TV.
Plus the MLB TV Mosaic alone is worth the $5. It allows you to easily scroll through live box scores and have anywhere from 1-6 games up on the screen with just the click of the mouse. It is really the only reason I enjoy MLB.TV.
I just subscribed... it's frickin' brilliant! The quality is excellent, and being able to switch from one game to another is fantastic. I wish the NHL offered something similar.
