ASM vs ACFS for 18.7 on X8-2M ODA

We just got our two new X8-2M ODAs installed and are debating whether or not to use ACFS. We had to do so on the X5s we're migrating from, but I never have liked the idea of the ACFS layer on top of ASM, especially for DB files. I've looked back and found various arguments, but they seem tied to more-or-less specific architectures. These X8s are standalone, bare metal, non-HA servers, so none of the RAC-ready junk we had to deal with in the X4s and X5s.

I'm pushing for only ASM for DBs, but maybe an ACFS filesystem for regular OS files.

What are some experiences, recommendations, pointers for us to consider?
