Doesn't matter what you use, as long as you accomplish everything.
Flow checks, acronyms, mnemonics, it's all there to do the same thing.
Take a pick and choose whatever you are most comfortable with.
I highly prefer flow checks since you only have top remember where to start, from there you check everything you come across.
Some airplanes (due to their archaic layout) are better suited for a mnemonic/acronym.
Example; I flew a Mooney a while ago, first flight on type, late 70'ies model.
Weird combo of old and new avionics/guages and dials.
Analog CHT/EGT/turbo temp and digital engine analyser system scattered all over the panel. Didn't even know where to start with a flowcheck.
So back to BUMPFICH/GUMPS on that one.
