   Sorry for the slow turnaround - hope this is heading in the right direction. Still nowhere close to the performance of more primitive types but about 2-3 times as fast as the previous implementation
   
   ```python
   >>> arr1 = pa.array([list("abc"), list("def"), list("xyz")] * 1_000_000)
   >>> arr2 = pa.array([list("abc"), list("def"), list("xyzz")] * 1_000_000)
   >>> %timeit pc.equal(arr1, arr2)
   463 ms ± 5.33 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
   ```
