Elementary vs middle school self contained

This is a question for those who have done self contained at both the middle school and elementary level. Currently mod severe middle school teacher in a rural title one district and I love it for the most part. Just the only thing I don’t like is my commute. It’s very out of the way. There’s an opening at my son’s school which is ten minutes from my house and it’s a higher paying better rated district than mine. I’ve been doing sped for three years now (one as a para for scd and one as inclusion which I do not like and now one in scd as lead). Whats the big difference between middle and elementary self contained? All I’ve ever known is secondary. I just recently got my k-12 sped license and being a male at an elementary school might be a big boon for me I think mostly. Thoughts?
