<snip> ESPIE beats everything. That's the point. If (a.) all you need to trap is program checks; and (b.) you expect a bunch of them -- use ESPIE. </snip>
I'd say "If ...you expect a bunch of them" then make every effort to redesign your application. Because "no program check" can be thought to beat ESPIE by even more than ESPIE beats other forms of recovery. I'd also say "if you're actually interested in debugging, you're much more likely not to want to use ESPIE". ESPIE was intended for FWIW, as Binyamin noted, ESPIE can be used only for problem state programs.
