Hi Matt Both are fine machines and they are usually hard to find in decent condition. The N6 is larger with a bigger grain tank while the R50 is newer and worth more. Either machine would have infinitely more capacity than your G. I upgraded from an l2 to an R60 for 2 reasons. My family wanted me to get a combine with feed reverser as they worried that I might get a heart attack or something unplugging the l2 in tough beans. Secondly, the l2 grain tank wasnt large enough to make 1_4 mile rounds in corn with a 6-row head. After Hyperizing the R60, I wouldnt go back to a conventional if I got it for nothing. Tom in MN
