All in all - no, it doesn't matter, but doesn't hurt if you want to switch out your needles I guess.
I agree with pag in that it probably does not matter a whole lot. My only thought would be if you stay with the sharps for gear making you won't run the risk of having the wrong needle in the machine when it might matter. For very light woven fabrics like we use for gear a ball point needle can cause the fabric to push into the throat plate causing no end of grief.
