It will depend on what discipline, your pocket book, your skill level, etc..
There is no one "best" for everything. A Hammerli Olympic grade target pistol may be an excellent firearm for one specific competition, and fare poorly in another. A Ruger Mk III may be the leader in another competition, but is far to big for easy concealed carry as a defensive firearm. Depends on what you want the pistol to do.
Glok 22

The Browning medalist was the best by far.If you can find one,these were made from 1959-1974.

There is no ONE best for everything. A small .22 carried as a defensive firearm would do poorly in Olympic slow fire pistol competition, and the Olympic pistol would be a poor choice for carrying concealed. You would need to refine your question a bit. And then it will still be a matter of opinion. Some people like strawberry, some like chocolate, some like Ruger, some like Hammerli, and some like revolvers!
How much can you sell a car for? Depends on the car. Your answer depends on the pistol. There are inexpensive 22 caliber "pocket" pistols that sell for about $50-75, and VERY pricey .22 caliber Olympic competition pistols that are $1000- and up.

Gun shops, gun shows.
You will have to provide the end use for the pistol for anyone to even begin to try to answer this question. Also, your budget.
There is no ONE "best" of any firearm. The Ruger .22 autos with target barrels and sights are among the most common, the High Standard Supermatic Citations have been used in competition for years, and Olympic Match quality guns like the Hammerli have been used as well.
