I am still on Stock ROM. As the current version of TWRP is not capable of doing backups/restore and the modified version, which does, isn't capable of flashing img files, I am still on hold until there is a fully functional TWRP for the F1 Play. Once that is available, and I can easily and safely go back to my backed up ROM, I might try something different.
As the Stock ROM is working fine for me I don't feel the pressure of moving to a Custom ROM, which might bring annoying bugs. Currently I live by the rule "never change a running system".
