I have 20 points for both HYS and MCS and I choose MCS (and failed, but no regret as I've tried). In my view, MCS is still a lot better than HYS.
I live in Net 34, so for 2nd round, I will still choose MCS as my 1st choice in part A and HYS 1st choice in part B. Looking at the campus and uniform, my daughter loves MCS way way better than HYS.
