We more or less do it equally. I load the dishwasher wrongly and (not sure how this is even possible) unload it wrongly compared to when she does it. I vacuum badly (eyesight is perfectly attuned that I can't see detail on the floor with or without my glasses) but at keast I'm capable of winding the effing vacuum flex back on properly. We share cooking, buy she's a veggi so I don't do that right either. We do our own laundry. Despite being a neat freak, she never puts things back in their correct place and is happy to leave stuff laying in the way for days. I do the same, but then I'm not the one to moan about the mess even though its largely hers!
I'm the only one who does the stuff that doesn't really matter (or count), like: wash the cars, service the cars, deal with insurance and MOTs, do any maintenance around the house, fit kitchens, lay floors, fit bathrooms, fix the heating, build sheds, lay decking, replace or repair electricals, do plumbing, hang doors, replace locks, look after the av system, mow the lawn, service the garden tools, wash the paths and decking, do any digging or heavy lifting ... but only she cleans the bathroom so in our modern feminist driven utopia it's a fair division really.
