I have not found Remington caps to be better - or worse - than CCI caps. They are a slightly different size, and so will work better on some nipples and worse on others.
The geometry of the nipple/hammer interface is key to cap function and it's a very complicated thing, influenced by many difficult to control details. It varies from model to model and even from gun to gun within a given manufacturer and model of gun. We tend to want to simplify the problems we find by saying that one brand of caps is better than another, when the real issue is that one size/brand may satisfy the geometry better than another on just that one gun. It may be completely different (or the same) on another gun or model.
So, whatever I or others may recommend may or may not work for you. In short, it's a crap shoot. Based on that, I certainly wouldn't order a case of any one size or brand of caps for any one gun without having tried a hundred or so first.
Treso nipples have a good reputation; whether they are worth the $20 or so per gun depends on how bad the current combination of caps/nipples are on the gun you have. They are a 'drop-in' solution; no sanding/fitting is needed. One advantage they have is that you know the cap size they are intended to use, so that pretty much narrows the search for caps down a bunch.
Now for a short rant: Nobody specifies the length of after-market nipples. You can't buy, or even know in advance, how long the nipples are, and yet that is one of the most critical pieces of geometry in the hammer/nipple interface. So, truth be told, you have no idea if the replacement nipples you order will truly fit and function in your gun. One thing you can be sure of is that they won't be the same length as the original nipples; whether they will work better or worse is just a wild guess. But, you have no choice. Spend the $20 and hope for the best...end of rant.
