I've heard good things about br2 but have never used them. Have a pack of 100 but have 2000 wrl... So that's what I've been using. Happy so far with them so no reason to check out the cci, rem, or br2s that I have in small quantities.
I have been loading for a little over 35 years so I will pass on what I have learned about primers. It all depends on caliber, case, powder and bullet you are using as to which primer will be the best. Primers DO MAKE A DIFFERENCE. But so does case, powder, bullet and the caliber. Now throw in different lots of each of these and you have more variables. Moral of the lesson. Have a large amount of each lot number when working up the perfect accuracy load which is really hard to do these days when you can't find what you need.
I am not really sure from your question what you are looking for. As far as sensitive primers it has been in my experience that Federal primers are easier to set off. I have found that they should not be used in semi-auto rifles that have free floating firing pins like the M1 Garand, M14/1A. or ARs. You will have slam fire issues using them, at least I did. The firing pin in these rifles does not have a spring that holds the firing pin from going forward when the bolt closes. If you look at a round that has been fed into the chamber from the magazine after firing a round before it you can see a light dent in the center of the primer on most primers. Federal has a thinner cup and is more sensitive and will sooner or later be set off by this light striking of the firing pin.

To clarify. I shoot pistols with light trigger pulls. In order to get light trigger pulls you often have to have a lighter main spring. Some primers make a heavier impression than others. Which primer makes the best impression would my guess be the thickness or type of alloy used. Is CCI softer than Win or Fed etc

Federal is more sensitive than all other primers. Their cups according to my experience is a little thinner or softer than CCI, Win and other brands. For this reason you will never have a misfire in a gun with a weaker firing pin spring. I had misfires with CCI in my .357Magnum Marlin Rifle. With Fed205's I never had any. The other reason I like Federal is because they are the most consistent and give very low standard deviations. Most championships is won by Federal primers.

Thanks for the response. Your answer Reloader 222 was what I was looking for. I have a nice 686 .357 I pack while horse packing and wrangling in the high country. 3.0lb trigger. Shoots well but had some mis fires with some loads that I wasn't sure which primers they had. Federal match is my go to primer for my bench rifles. I've always trusted them. I'll stick with that brand for pistols too.
