I use the super swage for my 223 brass. I trim off the press anyway, so I just swage after I trim with a CTS trimmer. The dillon 1050 is the only press, I have heard of, that will swage primer pockets automatically. Some people run a 1050 with a dillon trimmer and the press swages while they trim. They then clean the lube off the brass by tumbling and then run a second tool head for loading the ammo.
The 650 and lnl should be about the same and in the same boat as my 550-none of them swage. I run a dedicated tool head for my sizing die, for rifle brass. I use dillon spray lube as one shot has proven to be not good for rifle brass (I use one shot for pistol though). I size a batch of brass then tumble, trim, and swage. Then, I load up the tool head with a universal decapping die when I load 223, so that any corn cob is removed from the primer pockets. When I load 30-30 and 30-06 with cast boolits, I use an RCBS expansion die instead, so I have to manually check primer pockets. The first station is also for priming. Second station is powder and third is seat/crimp. Fourth station is left open.
The 1050 really made sense for crimped pistol brass, because it doesn't have to be trimmed and can be loaded in one pass through a progressive press. 9mm would jamb up my 550, when I got one with a crimped primer pocket. I didn't want to size on the dillon, swage off the press, then go back on the press, when the 1050 does it all with one pull of the handle.
The 1050 also seats the primer on the down stroke vs. the other dillons which seat on the up stroke. Down is much nicer and it is adjustable. You also get more stations for powder check dies or a bullet feeder.
It sounds like the 1050 is a more expensive or complex machine than you are looking for (although it is easy to setup the dies once the machine is converted to a particular caliber-I have never changed calibers, but I do readjust for different components) so the 650 and lnl are still very similar. I have never used the lnl, so my first choice would be dillon.
