Drysuits are the easiest thing to put on.. they are like normal clothes (I use trilaminate) ... I'm not sure where it comes the story that they are harder to get on? Maybe for very skinny people, they are comfortable to slip into that sticky neoprene... but i'm always pissed of when I have to wear even a 5mm.
But for having to squeeze my head and hands through latex seals, always fearful of tearing one, I might agree. I lube them up to aid the process. For me, it's a toss up whether a drysuit or wetsuit is more annoying to don/doff.
