What ever you go with just make sure you can get parts. I personally hate waiting for weeks for parts on what i call off brand due to the 3 lhs not carring parts.

Now on the MG16, i have one and like it alot. I did change the metal bushings on the knuckles and had CBP make me a rx pack to get away from the 4AA rx set up. Works much better. I want to swap pipes but there is not any thing that would really fit easily so other upgrades are not really an option right now.
It is a very durable little truck. I thas taken a few tumbles and cart wheels and lands on the tires and keeps going.
