I'm not 100% sure, but I believe that ARC was acquired by a private equity firm some years ago. Consequently, ARC may have more financial wherewithal to maintain/improve their market presence than does CJ.
As to their relative sonic merits, I've owned several pieces from ARC and generally liked the sound. I have only auditioned CJ (long ago) and agree withe consensus here that it seemed a touch warmer. However, I'm not at all sure that that delta equates to their relative market position today.
