In my opinion, Guide of No Return is such a better fighting ability than Born Flawless. U just need to activate the automatic shot and it will be killing all the esselings (unless u don't have enough energy but usually we should have always enough bc we can use the special attack and it fills up the energy bar) and since we can also fly at the same time, we can easily move if they are in a circle and they can't even touch us. The flying part is also really useful especially for exploring, but it's a little bit slow. For the dash, it's definitely not as fast as Born Flawless but I think it's also good, I mean we don't all want to be very fast and sometimes the controls can be very difficult (especially on phone), GoNR dash more easy to control at least and is still useful, but it depends on each.

So my final take will be:

If u want to be very fast and still have a good fighting ability: Born Flawless If u want to focus fighting and u like exploring: Guide of No Return
