There's no "wrong" way here. There's a trade-off of having the simplicity
of assigning the data pins to any pin in any port of the processor with the
added complication of breaking up the data byte and individually twiddling
those pins vs. using a specific block of pins and passing the data in one
write (or two with a shift in four bit mode). It's a classic engineering
problem, solve it in hardware or solve it in software. "Best" depends on
how you cost things.
