I guess the 10/22 might win for me but it depends of course for you on what gap is best filled.
Do you have a small revo - snub or close to it? Do you need a small SD gun? Do you have a .22 rifle at all? I think it has to be decided by prioritization, difficult tho that might be.
Hopefully too - what you don't choose now might well remain tucked away, against at some later time, another chance to help her out.
