About ten years ago I also replaced my 700x32 Gatorskins with 700x32 HS 420 Marathon Green Guards. I found the Marathons to be so sluggish around town I put the Gatorskins back on for an upcoming tour. The "new" Schwalbes hung in my basement for a decade.

Fast forward to today ... After having to electrify my bike, I started having frequent flats using knobby 700x43 gravel tires, quite a chore to repair roadside with a motor assist on the rear wheel. I pulled the "sluggish" Marathons out of storage and replaced the 43s. They silently fly along with the assist and so far no flats!

Not an endorsement for ebikes, just pointing out the flat resistance of the Green Guard. If I could still tour on a conventional bike I'd likely use the Continentals with an occasional flat.
