On lift vs tilt.
You can operate the lift in a smaller space than the tilt, but it's truely a pain in the ass to scrape the sides down. The lift is also more forgiving in terms of making a mess, and you can add ingredients easier while the mixer is running.
I've read that the lifts are better for people who make a lot of bread, and tilts are better for people that do a lot of lighter mixing, but I don't know. I do both, and apart from the scraping, am happy with the lift, and that's a process that, while irritating, quickly becomes rythmic and doesn't seem so bad the more you do it.
As a gadget guy, I come down firmly on the side of the lift, on the all important to cooking basis that the lift is, like, way cooler than the tilt
edit: You can also adjust the height on the lifts by small increments, while I believe that on the tilts you're stuck with the factory standard.
