So Rodney is the answer to both questions?
Not much point to this, but...
Rodney vs Boohma
Damage : Boohma has clear advantage; 2 more damage
Low pills battle : Boohma is slightly better, but only marginally. Rodney has same functionality but in weaker form.
Medium/High Pills battle : Rodney wins with big margin
Resistance to SoA : Rodney beats Boohma 10-0
Resistance to DR : Favoring slightly Boohma, but baseline is -3 min 2 thus they are almost equal.
Verdict: Rodney wins because its way more stable and has wider range of use. Boohma can be used when squeezing every bit of extra attack matters - namely Boohma has special place in survivor ELO when you have less pills than opponent from beginning.
