rebs: Its really a matter of is it worth it to you. There is no one or even right answer.
You really don't HAVE to clean any case. You can primer pockets with carbon in them, wipes the lube off the case and shoot it.
I don't like it, but there is nothing technically wrong (maybe some carbon build up in the chamber)
The wet cleaning has them coming out clean as a whistle and nice and bright (and buy a Walmart veggie dryer to dry the cases not the gun ones, same thing at 1/4 the price)
My brother uses the wet system and loves it. His garage is setup for it with water and drains.
I don't, my shop is not amendable to it so I would have to sue the Kitchen and that got multiple issues (my the house frau aside!)
I am fine with the polishing tumbler, primer pockets clean out with the RCBs prep and it takes the lube good off nicely.
I have a hand tri tool for 223 that has a pin on the end that is perfect to punch out any stuff in the primer holed (easy to do as they are put in the re-load tray upside down and I can see all the pockets (then burned right side up after they are primed)
An advantage with wet is if you anneal with a induction unit, there is no smoke from the carbon inside the case. Its as clean inside as out. It does affect the timing settings a bit.
With my setup its not a tempting option, I just resize, dump em in the tumbler for 8 to 16 hours and good to go.
I do have a Calder (from my wife) that I put over a cut down 5 gallon bucket that I sift out the media from inside, turn them upside down in group0s of 5 or so, tap them, then put them in the Stainless pans.
Good system, I am happy with it but this truly is a preference and what you have in the shop or garage setup wise to allow it to work.
