I prefer QD scope bases on my DG rifle. I had Leupold QRW bases and rings on my pre 64 Win 70 in 375 H&H in Africa but changed to Leupold QR bases and rings upon my return.
The QRW's are very low, very compact, and very easy to manipulate. They are very secure and return to zero very well. But, and this is a big but, that easy to manipulate lever caught on anything and everything!
The biggest detractor with the QR levers is I about half the time need a leatherman or other pliers to loosen them after they have been on a while.
