More Density, a John Deere 568 or a New Holland RB560/ CaseIH RB565?

Any opinion is a good opinion,

I have a John Deere 568 and it has been a good baler but I am getting close to 25,000 bales on it and am needing to upgrade while there is still a little value left..... I do about 3000 bales of hay and 1500 bales of straw each year on one baler.... I heard from a neighbor that said they went and traded there 568 and 569 John Deere balers for a New Holland RB560 (which is identical to a CaseIH RB565) and they were blown away on how much more hay that they can put into a bale. When they said that I think I started to drool because a lot of our bales are sold and the heavier smaller bales the better for when it comes to freight...... So I was just wondering if that is true:

 

-Does a RB560 & RB565 have more density in the bales compared to John Deere 568.

-Could I get over 1000 pound Wheat Straw/ Barley Straw bale out of a RB560 & RB565 baling right behind combine (with my 568 I would be very lucky to get a 1000 pound straw bale with my density to the max high and bale at 71")

-Does a RB560 & RB565 bale rotary straw pretty easy, as easy as a John Deere 568
