>>4325829i have a 1d and 1ds mii which i got used to, so it's not TOO far a stretch to step backwards, but there are some quirks like you mention. drive mode being a side button under the flap instead of where "ME" is like on the newer cameras, and the custom functions. aside from those though it's not bad actually. but like i said, i'm used to 1d layout. coming from another system it might be shit, not having dedicated buttons and needing to memorize combos, etc. especially in the dark or when needing to change fast. I'm only taking literal shit snaps with my cameras for a laugh so it's perfectly fine.
