The reason every 22 seems to like different ammo is the guns are by and large cheap and the bore diameter on almost every gun is different. Only with the expensive guns do you get consistent match barrels.

If the bore is large, the gun will shoot HV ammo best, as the bullet obturates to fill the bore. A gun with a proper match barrel, will shoot SV ammo like a house a fire.

The old Federal Classic and the CCI Mini Mags work in the most guns, over all, as both are fairly consistent, are HV and fill the bores. The 40gr solid delivers the most energy at 75 to 100 yards as they simply weigh more at a near enough velocity to overcome the difference in speed. Four grains is 11% of a 36gr HP bullet.
