which one should i use Bud Blood or Open Sesame

Im using Fox Farm nutes for a couple plants and Advanced Nutrients on 8 other plants. I like them both. Im bout to go into flowering and was wondering what u guys think is best Bud Blood or Open Sesame for the first couple weeks of flowering? And is it cool to interchange the two brands.bud Blood is more expensive but is it that much better than Open Sesame? Anybody with experience on the two help me out.

come on guys help me out...

I used bud blood and it worked great for me
It also came free with big bud and carbold when u order nutes off www.globalgrow.com
Its pretty sweet buy all base nutes and get boosters for free hehe

ok cool i picked up some open sesame imma see how good it is.
