The drawback of something like the ‘574 is that there’s no way to see the internal state without outputting it somewhere (like the bus). So for debugging and demonstrator type projects, the 377 is fine because you can connect it to some LEDs as I have done, and then into a bus transceiver, but if you just use the 574 in the exact same way, you ALSO have the option to reduce your chip count since you don’t need the 74HC245. Drawback obviously being fewer blinkenlights.
