Verdict
The clearest difference is price: TETSUO at Free against SlingFighter's $2.99. TETSUO also leads on ads (none vs shown) and iOS requirement (7.1 vs 13.0). SlingFighter's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (11 vs 1). On rating, in-app purchases and device support there is nothing between them.
