Can someone suggest a ROM that will definitely be compatible with my G920F?

I'm somewhat of a noob when it comes custom ROMs. I was an avid flasher when I had my S2 but things seemed to be a bit more straightforward then. I've been waiting for the MM update for what seems like forever and simply can't wait any longer so I rooted my S6 with the intention of just flashing a MM ROM. But I'm struggling to find a ROM that I can say for certain is compatible.

I'm not asking for the best ROM, I just want one that won't screw anything up. Thanks in advance. Device details below.

S6 G920F. Rooted with Unikernel v8-0002. TWRP 3.0.2-0.

Baseband: XXU3COI9

Build #: XXU3QOJL
