I've used and continue to use a variety of Marathon models including the standard Marathons, Supreme, Racing, and Plus. They are all solid tires, and they all feel different, but I think width plays a bigger role in ride feel than the difference between models.

The 42mm Supreme is my favorite in terms of overall ride feeling, with Racing in 35mm being quite nice as well. Standard Marathons in 25/28 feel a bit harsh to me, but in 50mm they're pretty similar to the Big Apple which I think are great tires. I've found all Marathon models to be very durable and puncture resistant. But I think puncture protection can only be evaluated on a statistically relevant sample size and not anecdotal reports from individuals.

I tried the Plus model on my commuter but it felt "dead". I continue to use them on my cargo bike though because they seem to be about as tough as you can get and messing around with a flat when loaded up with kids/cargo/etc is not something I ever want to deal with.
