Can’t claim to be an “expert” but I’ve been running normal Marathons on my winter commuting bike for a few years and they’re fine for the purpose. Sounds like similar road conditions to yours – mud and stones washed out of banks, potholes etc.
I wouldn’t say they’re too draggy, but then it’s not an easy comparison (Marathon 700x32c at 70psi on a heavyish bike with hub gear and hub dynamo vs Gatorskin 700x28c at 90psi on much lighter bike with derailleurs). The winter bike is certainly a bit slower, but I don’t think the tyres are entirely to blame.
Not sure about all the other versions, I’ve only used the normal Marathon.
