I used to use the old RCBS press mounted swager, but I hated the violent up stroke that knocked stuff over on the bench. However, it did a perfect job on both large and small pockets with a nice radius and a firm pocket.
Then I bought a Dillon super swager to speed things up because I have several 5 gallon buckets of .223 to do and I buy every cheap mil-surp 30-06 stick of brass I come across. The Dillon is very nice, very fast, can destroy a primer pocket in a heart beat if you aren't lined up right, but does not put quite as nice a radius on the pocket, but certainly useable.
