I've used them both. I like Jessicurls a bit better. It seems a little more moisturizing to me and I like her Citrus Lavender scent.
The CJ one would be my 2nd favorite DT though. It is very good and I like the smell but not as much as Citrus Lavender.
2b/3a, primarily use Jessicurl and DevaCurl products, Curls Hair Tea conditioner and various gels. I'm modified CG-ish since 5/04.
