Having used both (Square Deal B uses the 550 primer system) the XL650 is head and shoulders better.
More reliable. Less prone to fouling build up. Safer due to stacking of primers being impossible. Also has a far superior method for dealing with an unused primer in the rotating disc: if you have to scrap a case in process just toss it and keep on trucking; no need to pick up the extra unused primer as it will simply advance in the disc until falling into the unused primer ramp where it will be deposited for you to pick up at your convenience.
One other advantage is that the XL650 primer system is considerably more robust, and requires no fine tuning or adjustments at all.
