The big question is do you only want the scope for hft? If so the fixed 10 mag sniper style scopes seem to be the choice.
I also have a Bushnell Legend 5-15x40 and find it fine for hft. Like someone else said the mildots arent spaced well for airgun use. 1 dot down is 45yards for me (.177 30y zero). I like the chunky reticule and the clear optics. Focus is excellent which is good for HFT as you cant adjust your parallex once shooting.
