A good hood and 20 or 30 cold water dives in a ds and I think you'd change your mind. It's true the last 5 min or so gearing up I always ask myself why do I do this... and then I hit the water and all that goes away.I did all my UK dives in drysuit so was never really cold, but all the protection just makes dives not fun for me, especially hoods.
And then there's getting all the protection back on when they are still freezing wet for the second dive.
My wife doesn't like cold water because of the gear... I keep telling her it's really just because she's not comfortable enough in it yet. I need to stop otherwise I'll end up having to buy her ds
