I assumed the word "have" implied "free" at which point F/A is the no-brainer winner! Really.
If "have" means "pay for yourself" then supressor is the no-brianer winner! Really.
If "have" means "with you when the Zombies" arrive, then suppressor.
If "have" means "with you when the hoards of living [fill in your personal nightmare]" arrives, then probably F/A as I would need a force multiplier to deal with "hoards".
Personally, though, if I were to rent something or have to keep, I cannot see a situation where a can of any kind would beat out a BAR.
