AR-V & AK-V owners

Trying to decide between an AR-V or AK-V (no I can't just buy both). Does anyone have a weight in both (with comparable barrel lengths)? Also anyone had experience with one running more reliably than the other with both FMJ & HP? FMJ is usually whatever I can get my hands on for a good price HP are typically 147g. I've heard of some people having issues with 147g flat nose not sure if that's the case with 147g HP also. Which ever way I go it'll more than likely be one of the builder sets. Thanks in advance for any input.
