I think the reason that handling interrupts in ESPIE is faster than ESTAE is simply that ESPIE sets an exit to the FLIH, whereas ESTAE sets an exit to the SLIH.

If data or addressing exceptions were expected I definitely *would* use ESPIE. I would save ESTAE for unexpected (well, expected unexpected) conditions. My opinion: no benchmarks, no source code.

You can also recover program checks from ESTAE(X).
