Before I dealt my N6, my local dealers provided a side-by-side comparison between an R62 (stock) and a 9650 STS (the smaller of the two green rotaries). I found the two machines VERY EVENlY MATCHED in corn, but preferred the STS in beans. The fewer moving parts and lower price tag of the Gleaner kinda stuck out in my mind, though. I ended up ordering a C62; - the machine I ORIGINAllY intended on purchasing!
