I agree that your example is snythetically equivalent. The only difference in your example is that with one scenario you'll have a debit (debit spread - Reverse IC), whereas with the other you'll have a credit (credit spread - IC).
Although the bid/ask spread is wider, typically you'll save on commisions and bid/ask cost with a credit spread, as expiration may preclude the need to enter a closing trade on all four legs.
Nonetheless, whether or not it's a DITM IC or a DOTM Reverse IC, I believe it's a good risk:reward bet... as long as the asset will have a material movement in either direction.... This is why I would enter the transaction (DITM IC or DOTM Reverse IC) at least 3 months out...
If there's a major hole in my logic, then I conceed...
