I have used QED, TGQ, and Honeybee glycerin base soaps. Of the three, Honeybee is my favorite on a performance basis. The addition of shea butter and clay make for a nice lather. I don't love the scent of many of the Honeybee FO soaps that I've tried, but the EO soaps smell great. I think I'm just partial to stuff that smells natural. I like the lavender/rosemary/peppermint. The scent is somewhat mild, but very nice.
The only ones I have used are from The Gentleman's Quarter so that is what I would probably (or maybe something from one of the Sues, or one of our other fine vendors) purchase. The smell great, are easy to lather and I get a very close shave with them.
I have used HBS, QED, TGQ, Mama Bear, Col. Conk, and VDH.
HBS, QED, TGQ, and Mama Bear are all very strong contenders and great soap.
For performance, I prefer glycerin soaps with added clay (usually bentonite), which HBS and TGQ both have. For some reason I prefer HBS over TGQ, although they are both amazing.
For scent, you simply cannot beat a tub of QED.
I must also mention Mama Bear as her soaps are quite good. I still kick myself for selling my Mama Bear soaps.
