I really like the SWFA 3-15 FFP and Bushnell 3-12 FFP (G2DMR reticle preferred) for all around scopes on air rifles and .22s. Both are FFP/mil/mil so they match the optics on my larger rifles.
Both offer good mag ranges for both close in / brush shooting and also some target work at longer distances, both offer close in parallax (6Y on the SWFA and 10Y on the Bushnell), and both have a good amount of elevation travel if you want to make some long shots.
For the last 2 years or so I've been running the Bushnell 3-12 x 44 FFP G2DMR on both my 10/22 and my precharged air rifle and really like them.
Having had both the Bushnell and SWFA I like the wider mag range and more top end magnification available that the SWFA offers but the Bushnell has better glass and more importantly a better reticle in the G2DMR. The SWFA mil-quad is good but the G2DMR gives far more options for elevation & windage holds. The Bushnell does have the tighter eyebox, especially up around 11-12x.
The upcoming Bushnell LRHS looks really good too; if it was a 3-15 or 3-18 it would be near perfect IMO.
