crf150rb vs crf230f

I have a 2012 crf150rb and put it up for sale on marketplace. I have a few people that have reached out about trades (all straight trades btw). One being a 2016 Honda crf230f that looks to be near mint. Another being a 2009 kx250f that has had (supposed regular maintenance, recent valve adjustment, new carb, new rear sprocket, and new grips). Lastly, I received a trade for an 07 rmz450. Also looks pretty dang good, but I’ve read online that it only has a 4 speed gear box. Any info would be greatly appreciated.
