No experience of the gameking to be honest but recently bought a HW97 that had a milldot Gold Crown Air king ontop , what a nice scope with surprisingly nice glass imho , its now on my .22lr and if the gameking is as good then would be a good choice ( ive tried soo many scopes zeiss, s&b, burris, Nikon , bushnell etc etc ) and sometimes im really impressed by scopes that you really sometimes you think wouldn't offer that much , another one was an edgars brother optimate,thats now on my other .22lr
cheers
