Sloppier in what respect?

There's enough play in the biscuit slots, and enough variability
in the thickness of individual biscuits, to allow for noticeable
misalignment in an edge-to-edge glue-up, enough to leave a ridge
that's too big to remove with just a few passes with a card
scraper. I found that I can get better alignment, faster, without
the biscuits.


Then your either using wrong sized biscuits , wrong size blade the
machine incorrectly or the machine has a fault .



I think you just about covered every thing that can happen when you use
a plate joiner. Pretty observant, you are.
