>>42021583guts gives fuckhuge damage boost, burn cuts attack in half except this is negated by guts, and between toxic and burn, burn only does 1/16th damage every turn vs toxiced's 1/8th-1/4th-3/8th-etc.
between the two guaranteed guts activations its clearly preferable.
It's basically objectively better solar power and comatose at the cost of an item slot.
