Three-flute bits, absolutely.
I do low voltage electrical work (Audio/Video, Home Theater, phone & network cabling) and used paddle bits for a long time, but they bend or break when they find a screw, go dull quickly, etc- I started using the Irwin three flute bits in about 2005 and haven't bought a paddle bit since. These also fit any 1/4" extension, so extremely deep boring is possible, but make sure the extension doesn't allow the bit to wobble. For that matter, if you need very long reach to drill a hole, a second extension can be used but I wouldn't do this without the type that doesn't require releasing the bit to remove it. Irwin makes those, too.
