GMG -vs-Mak-1. Which is better for me? HELP!

So I have been using Traeger to smoke beer jerky. I would just set the temp on SMOKE, and after about 3 hours or so I would get great, moist jerky. Now I am ready to upgrade, but don't know which way to go. The smoke temp setting on my Traeger was about 150-170, which is perfect for my needs. I want a Mak-1, but the lowest setting is 170. However, the Green Mountain lowest setting is 150, which would be perfect. So---which one to get? My Traeger broke, so I do need a new one...
