Soooo.. Here you go, a side by side comparison of mugs.
From left to right, 58 Pattern plastic top mug, 85 Pattern PTFE coated, plastic rimmed top mug, stainless BCB Mk1 Crusader bottom mug, black non-stick coated Crusader Mk1 bottom mug and lastly the new BCB Aluminium Crusader Mk2 bottom mug.
As appears to be the herd opinion the Stainless Crusader Mk1 is the one to go for.
Mr personally? I agree. Plastic is awful to drink from, 85 is a pain to keep clean due to the removable lip, the black coated Crusader is pointless as it wears and chips and is difficult to ensure its clean in the dark. The alu Mk2 is dentable just using your hands and the heat transferring lip will burn your lip.
