Do these three artist remind you of each other stylewise?

Hmmm, well, they really don't remind me of each other. Hal Ketchum has a younger sounding voice. He reminds me a lot of Red Dirt Country, though he's from New York. Mel McDaniel has a rougher voice, more old style, and deeper. Gene Watson is probably the least unlike the other two. I think he has such a distinct voice! But...this is just my opinion, everyone's different. You're right, they are all good, so it doesn't really matter. Gene Watson is my favorite of the 3.
