If anything, measuring by weight only is better for liquids other than water. You try measuring other liquids by volume, you run into issues with it not matching as well. One container of milk may have more or less grams per liter than another. Maybe only a gram difference, but still.
Besides, a cup is always a cup the same way a liter is always a liter. A pound is a pound. You might run into crappy measuring devices that aren’t accurate, but the units themselves are standardized.
Metric makes some things easier, but other things harder.
Makes zero difference in end results.
