I have OLD .45 Vaqueros, .45 Blackhawks, and 32y/o eyes, and like them all equally. One shoots just as well as the other, but the Vaqueros do have to have a load worked up for them specifically to hit to POA, where the Blackhawks you can just find a load that shoots well and adjust the sights, which can be much easier. I can't really say I prefer one type over the other, and the fixed sights work very well for me once I found the load my Vaqueros like. I would say that if you will be loading, go with whichever you prefer. However if you will be buying ammo, go with the Blackhawk.
