ROCS by far in my opinion.
I was a member of the RCA for many years,, and while the MEMBERS were super good, I felt the ownership & management wasn't doing as it promised.
I had a few discussions with them directly and still things weren't resolved.
Basically, I felt that they promised (4) Journals annually,, and if you look at the actual publication, there are several issues that were never produced. Plus,, they often "combined" issues into one Journal. If I join, I expect the owners, or whomever is in charge to abide by their promises.
It was a major part of the discussion between many of us who are Founding Members of ROCS to assure that we did as we promised.
And ROCS hasn't failed in it's mission statement yet.
Add in the top-notch Quarterly publication, in full color, & top quality printing, etc,, makes it a pleasure to receive. And adding in the Special Edition guns they have had built for members who wanted something special, it's a throw-back to the early days of the RCA.
Now,, MANY members of ROCS are also still members of the RCA. And it's the heart of any collecting organization to have active membership. And while some have chosen to be members of one or the other,, it's a matter of preference.
It's MY,, repeat,,,,,,,,, MY personal preference to endorse the ROCS whole-heartily!
