Judge for yourself.
Left Stinger, Right MESA
Top Stinger, Bottom MESA
Before anyone asks: no, I didn't compare any other wires like this but a quick look at Kicker 4AWG says it's closer if not the same as MESA. My Radaflex welding wire is probably in-between Stinger and MESA but it is 100% copper with no aluminum tin job and slightly thicker strands.
Outer diameter of the Stinger and MESA jacket is arguably the same. It is actually a bit difficult to get the MESA wire into the 4AWG terminals on my amp.
Stinger is not significantly but notably more flexible.
You can see the winding of the wire is different between the two so that could be the reason the Stinger looks less substantial. Either case, guess which one I prefer.
Far as I know you can only buy MESA at dealers like my shop, for example. No idea the price... I'm using scrap wire. No I can't get you scrap wire.
