Hill vs Siemian why is there a debate?

We are short-handed enough as it is on O. We need Hill at TE and his goal-line plays. Simien is a better passer of the football. Is he a better QB overall? Don't really care to argue it, but as a team issue, we are better with Simien dinking and dunking while Hill plays his very important role, at least until Hill shows he's clearly better and we can sign some help at WR.
