The stainless ones are stronger, the aluminium ones aren't as strong as the stainless ones and can misshape it the valve sticks. Get a stainless one with an aluminium disk at the bottom for decent heat distribution.
Will do. Getting a 5lt one. Mainly for broths and the fact that I can be less organised with slow cooking recipes. Missus is in India atm and they are dirt cheap there. £20-ish.
