Trusting someone elses experiences isn't real smart. Each gun is different, or the one's I've owned have been. Best and then most reliable are two different animals. Best to me is cheapest, as long as the FTF rate is acceptable to me. If I get one or two per 550 bulk pack of Federals, I'm a happy camper. If you want the most reliable, pay a fortune and pick up some match grade ammo. QC on that stuff is pretty good, and almost all of it has priming compound spun into the rim.
Next time you decide you want to answer the question, go buy a box or two of every different brand/ bullet weight/ velocity ammo you can find. Its not going to be a cheap experiment. Then just go shoot a little. What I think you'll find is some is clean, some is dirty. Some is remarkably accurate, some isn't. Most of it will fire most of the time. If you ever get a misfire, take two pairs of pliers and bend the bullet out of the bad round. Dump the powder out on the grass (its good fertilizer) and then look inside the case. Almost always there is no priming compound in the bottom. Most of us rotate a bad round and try it again, but almost always it won't go off. If it does, you've got a gun problem.
With center fire ammo, most of us select Federal primers if there is any question of the strength of the hammer fall. I've never seen a problem with rifles. We've generally concluded its due to Federal using softer brass that's easier to crush (either primers or case rims.)
Difficulty extracting is a different animal. The idea behind using a brass case is that it has "memory" and after firing it expands to seal up the chamber, but then springs back to a shape close to its original. If you have brass (or a lot of brass) that doesn't do that, move to a different brand. With rimfire ammo, you could easily have a dirty chamber, or a rough chamber. It kind of locks the fired case in the gun. When it won't extract, you're trying to move either 6 or 10 cases at the same time and on the same stroke. An experiment you can play around with is using only one charge hole and seeing if its hard to extract from. Then move to another and repeat. Sometimes one of your 6 (or 10) is the problem.
I think difficulty extracting is more a gun issue than an ammo issue. You can polish the chamber or chambers if you like. Commercial items like JBs bore paste on a swab, chucked into an electric drill can work to clean up a powder/lead fouled hole. Its not quick, but then you don't want it to be because you could do damage if you went to sleep on the drill.
