I'll disagree with it being easier or more fun and will say that it slows things down considerably, an important consideration if you are reloading for 2 or more people and you shoot at least 2 times a week, sometimes 3.
Having said that, I do prime off press with .223/5.56 for the simple reason that you have to trim after resizing with bottleneck cases so I set the turret in my progressive so the sizer die is in the #4 slot and just feed the cases in to resize. I do the whole batch, then trim, prime off the press and then return the turret to where the sizer is in the #1 position, put cases in at station #3 which then charges in 3, seats the bullet in #4 and crimps in #5.
