I have or had all three, layouts were really close to each other, still have Pain and Toxic but changes layouts on the Pain.
I'd rate them in order of strength/usage:
Pain
Toxic
Doom
Love the Pain, will never get rid of the Toxic but the Doom, just didn't care for the reaction. Might have been to close to the Toxic but IMO, the Toxic laid out similar, is much more aggressive than the Doom.
JMO.
