Yes, I play guitar. As I have gotten older I definitely appreciate acoustic a lot more. I haven't played electric guitar in years now but I pick up my acoustic all the time.
I'm not exactly sure, could just be the style of Earle vs Clyne. Based on his other music Earle has more of a singer songwriter mixed with Alternative Country vibe, while Clyne often has southwestern alt-rock background. He used to be in a band called The Refreshments out of I think Tempe, AZ.
I wouldn't call Chester's a cover but I do always think it's kind of weird when bands keep the name but have a new lead. I've always kind of avoided Chester's STP but that was really good.
His interpretations are great. He does not try to add his own spin to songs. He was a fan of STP and wanted to give STP fans what they wanted, or something close to it.
