Read incoming attacks, evade at the right moment, and step back into range when an opening appears.

Verdict
The clearest difference is in-app purchases: Echo at none against Combat Strike CS Online's 7. Echo also leads on ads (none vs shown). Combat Strike CS Online's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price and update cadence there is nothing between them.
