Agree! The original style were there for a good reason. You are not doing your A/C unit a favor. These units were not made for that filter.
I suspect the reason for the original filter was issue of cost, size, and a few other reasons, none of which I'd consider "good" reasons.
A decent quality pleated filter resistance is measured in fractions of an inch of water column pressure. Fractions of a psi difference across the filter.
The pleated may be significantly more restrictive, but still not anywhere near enough restriction to affect performance. Ducting in the system likely has higher resistance to airflow than the filter.
