I agree with you, if the issue is which system you use to meter in the field. However, if the issue is film testing there is no doubt but that BTZS is superior in that it can give you much more useful data in far less time than Zone system type testing. Now, if you never use but one film or one developer both systems should serve you equally well. But if you happen to be someone who likes to experiment with different film/ developer combinations, as I do and suspect that you do as well, there is absolutely no doubt but that BTZS testing is superior in that it gives you far more useful data with much less testing.
