I have never compared to the two inner sleeves, but I use KMC perfect fits as my inner sleeves of choice. I think I might have 1 set of Dragon shield inners... but I am not 100% sure. Even if I did, I would not know which deck uses them. On the side of KMC, I have had zero issues with them. On occasion the Dragon shield outers were too tight for the inners, but I was able to forcibly get them double sleeved.
Wish could be more helpful, but I suggest trying KMC and see how that works for you. I have combined KMC with eclipse, Dragon shields, the non eclipse ultra pros in the chroma? line, but I did have trouble with older ultra pro sleeves before they transitioned to eclipse and chroma style. -Leon
