RoFs shoot out only a single blast of fire at a time, while Tack Sprayers shoot sixteen at a time. Although RoFs shoot significantly faster, it is incomparable even to a 1/2-0 tack shooter since one of those well placed can still at least put in twice as many tacks as the RoFs. They are great against low level bloon packs since it has infinite popping power but it is ineffective bloons not so far behind ceramics and virtually useless against ceramics and MOAB Class bloons. An upgrade like the tack sprayer for instance (which for some reason happens to be the one before the RoF) shoots 16 projectiles at once.

tl;dr The Ring of Fire shoots only one 'projectile' at a time while the other upgrades shoot 8 or 16. Ring of Fire pops ALL bloons in its burst radius. Its better than tack sprayer (why do you think its a tier 4 upgrade). At normal bloons, tack sprayer sucks. Its only good for fast bloons and MOABs
