Which do you prefer?

I'm wanting to build my own AR or AK, with help from an armorer/smith that I work with. I know the difference in calibers and all that, they're not really a concern. Just want a tactical-type rifle to add to the collection.

I've found a DPMS for $550, but would rather make it my own. Can get an AK for similar pricing.

I've shot both before and they are nothing like a bolt Savage, that's for sure! LOL!

What do you folks think is the best direction? Just wanted to get a rough idea of your personal preferences/experiences of which way to go. Leaning toward AK, honestly. Heard better reliability with them.
