The problem is that the preparation of the technique itself takes forever. The mutually exploding tags that Tobirama used? You'd have to make thousands of tags all set to summon a specific new tag that summons a specific new tag etc. You'd be busy for days if not months to set up a single use of the technique. And then you have to do it all over again every time you want to use it.

Compare that to e.g. Rasengan, which -once mastered- can be formed in the fraction of a second and endlessly re-used, and it's clear that mastery over ninjutsu is much better than matryoshka ninjutsu.
