I think loosing a leg would be inconvenient to say the least. A foot would be half way there of course. I think to be bipedal is kind of fairly basic to getting around.

I was once in a very strange movie where I did have to lose my right hand, and being right handed, that was really awkward. I was haranguing them for not making me lose my left hand!

Apparently losing a body part is pretty traumatic for anybody, whether it's a little finger nicked off by your local Yakuza (tattooed Japanese gangsters who sometimes cut off one of their own fingers as a test of loyalty) or whatever.

I keep my hands to myself because I don't want to lose body parts. Sometimes when I've been scuba diving I say, 'No no, don't point like that,' because this big grouper is going to come and go 'gulp' [and bite it off]. And so I'm pretty careful.

I would think you need to be mobile, so I want to keep my feet until last, and therefore the legs that attach them to the rest. Basically I'm a coward. I don't want to lose anything.
