Verdict
The clearest difference is rating: FireLine at 4.6 against Panzer.io's 3.8. FireLine also leads on update cadence (every 3 weeks vs every 2 months). Panzer.io's advantage is in-app purchases (none vs 7) and ads (none vs shown). On price, ratings volume and device support there is nothing between them.
