I have an RCBS Pro 2000 and load a pile of ammo on it. I just got a Dillon 1050, so my dillon experience is based on it not a 650.
It certainly works well, and RCBS warranty is fantastic, but so is Dillons.
The Pro 2000 does not have a case feeder, a case feeder is a wonderful thing. The Pro 2000 does now have a bullet feeder available but I have not tried it yet.
My Pro 2000 is older and does not have auto index, that is something I intend to upgrade, after using the dillon 1050 auto index is a serious advantage.
As far as quality of ammo, I don't think there is anything at all wrong with either.
The primer strips for the RCBS I find faster to load then I do the primer tubes for the dillon. If you have the cash for a primer tube filler from Dillon, then I'd say the tubes would probably be faster. You can buy CCI primers already in the strips too, but I hear they are cost prohibitive, I've never seen any for sale to know.
I don't know the entire story on converting a 650, as my 1050 is my dillon experience but I can say that the 2000 is much easier. A primer size change on the rcbs is one bolt. To change what primer is in the machine, you just raise the ram and pull out the current strip, so primer changes hands down go to the RCBS. You can get tool heads for both presses. The Dillon tool head holds the powder measure, the RCBS does not. If you want to buy tool heads for every caliber ( I didn't as I reload dozens of calibers on my 2000) the Dillon will be handier as the powder measure is set up, but that's a lot of money tied up in powder measures. As far as the powder measures themselves go, I find both do a very satisfactory job.
Compared to the 1050, the caliber changes are a breeze on the 2000, and I think the 650 falls somewhere in between. Again if your running case feeders and bullet feeders, caliber conversion times go up, but so do reload rates.
With rifle rounds I probably get 300 an hour and 400 for pistol on the 2000. Thats not humping too hard, no bullet feeder, manual index, boxing up the rounds etc. The Dillon should outperform that, adding the auto index would help, as would a bullet feeder, however the Dillon can get a case feeder and bullet feeder to step it up even farther.
I look back now and after using a case feeder, wish I had gone with a 650, however I'm not disappointed enough with my decision to change. Originally I based my decision on caliber conversion times, and on that note I think the RCBS still wins.
If your plan is one or two calibers in very large quantities (1000 or more before conversions), I think the Dillon wins, if you reload a very wide variety of calibers in smaller amounts (less then 500 before conversion) the RCBS wins.
Ultimately both companies make a great product, and I don't think you will be too wrong with either.

stupid move. It was an excellent press, very smooth, sturdy, well built machine! 
.i know theres lots of guy's on here with dilion presses and i just wanted to see if there was anyone as passionate with there RCBS as the dilion guys are. as this thread proves they are far and in between.
