Darcy's Botanicals pumpkin seed conditioner is my favorite. Nice slip, easy detangling, virtually eliminates frizz, unique scent. Tresemme Naturals Nourishing Moisture (to answer whisper_hotshot's question) is a close second, and would be #1 if I liked the smell. Like many of us, I try everything that catches my eye, but I always find myself coming back to TN NM. It's not quite as rich as the DB PSC, but it's inexpensive and widely available, which is a huge plus. Better yet, it was reformulated last year to move the good stuff (avocado and aloe vera) higher up in the ingredients.
I absolutely adore CJ Rehab, and would probably use it as a RO if it weren't for the price tag. I use it about 2x/week now.
