Could use it for a no stud run. It is possible, albeit horrible, to complete an any% run with zero studs (if you pick up a stud in a level you have to kill yourself at some point before you finish to get rid of it.

I can usually get the Wii strat in only a few tries (it's taken practice though). I haven't tried jumping on the lamp on Wii, but on PC I've never been able to get on top of it, not even when I was trying with a high jumper. I'd say the Wii is easier. Also the jumping practice from that will be good for 5-5.
