I switched to Armadillo Elites on my roadbike, which were better (or less worse) than the first Armadillos I had on it. I have finally given up on them for the road bike as I never had *that* many road flats anyhow.

Although mainly tubeless now, I still use Armadillos on one of my MTBs - and all of my kids bikes (they don't know how to deal with flats)

If you're aware of the compromises that you're buying into then I think they're good. What I can't comment on is how they compare to Marathon+'s - perhaps a member who has used both could comment.
