IMO the best and quickest brake is the Griner. I was able to go 430's in a heavy leaf spring car with it, shallow staging like I did bracket racing( and I am an old grandpa with probably slow reaction)
The Transact is actually a Griner knockoff, believe at one time Joe worked for Griner.
I ran the Griner for years, never an issue, no creep, and it was consistant.
