Welcome, CJ!
Yes, there are just so many options for high-gain tones.
Nobody's mentioned Guido Bungenstock yet, so I'll throw him into the mix. He does a high-gain pack that's put together from selected Rigs from many other packs. His Profiles are always pristine ("clear") and super-low noise.
I'll give Cililab an honourable mention for mojo; plenty of it there.
That said, for many years SinMix was the go-to guy for metal, and for many he still is. I've found his sounds generally to be more-edgy, which helps things cut through the mix, whereas Guido and Cililab are more-pristine, accurate and "phase-free". I say that 'cause that edginess I spoke of often is brought about with the help of angled mic'ing, which introduces comb filtering, something I'm personally highly allergic to!
