I'm big on the K&K Definity Pickup. These are passive, don't require a preamp and dirt simple to install. Your milage will vary. If you do want a pickup (certainly not required) , the K&K ones are best as they are matched to the 1000 ohm impedance.
Every time this question comes up, I always recommend the Gold Tone ABS banjo pickup. Installation is as simple as could be. It just clamps on to the pot brackets. For 179.00 you get the pickup and a small DI box for tone, boost, and volume control. Basically, the pickup is a microphone with a sensitivity closely resembling a Shure SM57. Tone is excellent and I have had zero feedback problems.
I, too, have an EMG. It allows my banjo to hang in with other amplified instruments in a church praise band. I can't comment about other products because EMG is the only one I've tried. But to my ear it projects the banjo tone with reasonably good accuracy.
No disparagement meant, but the entire ad copy for the new version of the Hatfield pickup relating to how a active magnetic pickup works and why the passive is superior is just plain wrong. Absolutely nothing wrong with marketing a passive magnetic pickup, but including all the pseudoscience makes it a bit disingenuous.
I use the Cling-On device on my RB-12. I use a wireless guitar device and a passive direct box now. The device is a Swiff Blackwing wireless guitar system. I can place the Cling-On anywhere on the head. It is secured by a magnet. I have used it in competition with a organ at church.
