I have the Lee quicktrim delux in 223R, 308W and 303Brit (also russian 54R but un-used) I think the end result is acceptable* its also a lot quicker than trimming to length and chamfering inner and outer as separate operations.
*However if you are skilled / careful I think you can do a better chamfering job as the chamfer is a bit "light" with the quicktrim.
