The big three, in American ammo makers, are Winchester, Remington and Federal. Coming in 4th would probably be CCI-Speer. A company that's been making large inroads is Aquila, out of Mexico. Then there is Ely, out of England, and RWS, out of Germany. Both of those are primarily target ammo, and are quite expensive. There are others - PMC, out of Korea. Armscorp, out of the Philippines. Wolf, which is usually Russian, but their 22s are made by RWS.
In my experience, Remington 22 ammo is crap. It's dirty. It jams. And it's not that accurate. Winchester is okay, but I've had real good luck, with all MY guns, with Federal Champion (Lightning/Power-Flite/Dyna-Flite/whatever they are calling it this year).
I emphasized MY guns, because 22s are picky. Some will work great with anything. Some only like one brand. Most are somewhere between those two extremes. Most guns seem to like Mini Mags. But the best suggestion I have for you is to buy a box of every type you can find. Shoot 'em from a rest, at a target. Keep records. Compare Remington Golden Bullet solids to Remington Golden Bullet Hollow Points to Remington Thunderbolts to Remington Subsonics to Federal Hi-Power to Federal American Eagle to Federal Champions to Winchester Super-X to Winchester Power Point to Winchester Wildcats to CCI Mini Mag solid to CCI Mini Mag Hollowpoint to CCI Blazer, to - well, you get the point. You might find out that the Mini Mags are giving you a one-inch group at 25 yards, and you're thinking that's great, and then you find that Remington Golden Bullets give you a half-inch group at the same distance, for less money. You really won't know until you try 'em.
