the best scope for a 22 is the same scope that is the best for a centerfire.........Use whatever scope fits your needs the best, the guys who i shoot smallbore matches with have scopes ranging from 20 bucks on up some of them even have leupold vx III's and zeiss scopes on their 22's. just because its a 22 dont be bashful when choosing a scope, My match 22 rifle i had a cheapo 3-9x32 simmons deerfield on it worked ok. We have a similar problem for me it was on over cast days it just didnt seem to collect enough light for my liking. It now has a bushnell banner 4-12x40mm scope and it gets plenty of light even at dusk on a overcast day. hope this helps you a bit.
