I have used both the Duremes and the Supremes at various times, and still have Supremes (1.6) on my Sherpa.
Very pleased with them. Both have been completely puncture free, in 8 + years, including some Supremes used by by son on his commuting bike.
Duremes are fine on trails, and bowl along pretty well on tarmac. I find the Supremes excellent on roads, and better than you would expect from their smooth tread on trails, canal paths etc., gravel and mixed surfaces fine.
Both will serve you well, I reckon, the choice coming down to main focus of riding I guess.
