As far as I know "im-switch -s" should run by user and it creates a link for IM to ~/.xinput.d/ko_KR so it's same as current situation.
It is very tough to say what is a consensus of opinion for Korean IMs. In my opinion, if priority needs to be set, scim should be default IM since it's in main now and it works for CJK. :)
FYI, one developer maintains nabi, imhangul and scim-hangul for Korean IMs so he gives us same quality though.
