Default pcm choice

I know its new and most people haven't received theirs yet. Im putting together an l76/tremec magnum and don't know which pcm to use. Car is a g body and summer daily driver, road trip car. Engine will have a tsp cam and cnc ported heads. I narrowed it down two options:

-Holley terminator x
-psi conversion harness

The cost will end up about the same. I have been weighing pros and cons and have reached a stalemate. I like the ability to run a DBC throttle body with the holley, but don't like the issues wiring the alternator. Also have to figure out the A/C trigger.

I like the idea of OEM simplicity, but feel like I am shorting myself on the flexibility of the holley.

Anyone have any more insight on this predicament?

Which will be easier to get tuned and dialed in correctly?

If cost and pros & cons are roughly equal then ease/cost of tuning and returning might be a factor to consider.

Personally I like stock electronics when possible in case something dies on a road trip. Not sure that would apply here because a fried PCM will be a pain either way.

That's another thought I had, bit just balanced out. My tuner wont tune the holley, but it has a self learn, so I can drive it wherever to get tuned after initial start.
