Having owned and still own both gas and diesel engines I can say with certainty the gas engines are less costly to maintain.
Since the diesel engines now require DEF fluid, keep that cost in mind. Also, diesel fuel now has less sulphur which reduces the "lubricity" of the fuel. I add fuel stabilizer to my GMC Duramax to counteract that. Injector replacement runs 3K. 10 Quarts of oil and fuel filters. Check regularly as diesel has a lot of water in it.
As far as getting them serviced on the road, you will find more gas mechanics than mercedes diesel mechanics, that's for sure.
