You have to pick one, but then you have to ensure that all the materials you're working with agree, just like imperial vs metric measurements.
But I'm not convinced that it helps, outside of semiconductors and tubes, because it can lead to a whole category of misconceptions. I see it come up reasonably frequently:
If you're taking a top-down or phenomenological approach, best to just start from observing that there is a property called "current" which has magnetic and thermal observable effects and quantifying from there.
