The longer sight radius of the SKS would definitely lend itself to better accuracy than a pistol. But you cannot make a SKS as short and handy. So it depends on what characteristic is more important.
If you are moving out of state I would definitely wait on the SBR conversion. You will need to verify the laws if the state that you move into. Moving an SBR into another state requires a notification to the ATF. So, I'd keep it simple and just do it once if that is the way you decide to go.
