Default Hf manifold or aftermarket

I have a 88 crx hf comming to me by next week and i was wondering what the benifits of using an aftermarket manifold over an hf manifold. besides the fact that i can run an external wastegate?

If I am wrong I stand corrected, but the main diffrence is the hf's are more prone to cracking over a dedicated log manifold

I've seen more cracked log manis than hf ones.
california cx/vx and 96+ sohc manis converted to turbo manis crack all the time where the spark plug O2 sensor is.

HF's better than a log any day.. but better than a primo after market... probably not.
