I have the Blackguard 50 & 52 set as well as a Brown Sugar bridge in different tele's. I have the 50's set in my 1958 Tele, the 52 set in a MIJ 62 Tele Custom, and the Brown Sugar in the bridge of a 1959 Telecaster, with an old Epiphone Mini-HB in the neck. I think that my ultimate favourite of these is the 52 set, but that is because I am a blues/rock player and so like the sound of these (though I really like the Yardbirds too). If you want the Keith Richards tone, then the Brown Sugar will nail it through a valve amp (the first time I tried it I had to play the intro to Brown Sugar - the tone was spot on). I'm not sure about the neck pickup on this set, as I have the mini-HB.
While I don't have a Yardbirds set, I do have a 1962 tele, and the sound is spot on for that (I have played the Yardbirds a couple of times). I really love the tone of these and think they are a great set for getting the Jimmy Page tones.
I probably haven't really helped you here, but if you want versatile, get the BG52, if you want Keith get the Brown Sugar and if you want a more mellow tele tone, get the Yardbirds.
