Your full tank mos stonewall is for sniper rushing, so you have a good chance to avoid ko and rush a sniper and win, however with 5ap per burst the pancor will not do enough damage and i fear he will outstim you or run away.
For town control its probably a good choice. But low damage output its just a big tank.
A crit tanker is another story with 4ap burst you can triple burst using jet with a reasonable crit chance and will almost always win against a full tank, at identical skill ( considering pancor requires any skill at all), your crit chances will make a huge difference.
However you have 50% chance on average of being koed by a sniper.
To guide you furthermore id say a crit tanker beat a tank, beat a sniper unless he rolls a ko, can fight a burster.
A burster is an anti tank build in two hexes you can take down a full tank. Weakness is low ko resistance .
A sniper is an anti sniper / burster / no stonewall tank.
The more friendly build you can go with considering the current state of pvp is stonewall tank with brof, its a popular build and doesnt require any difficulties to play, you are resistant avoid KD, have 50% less chance to be Ko and with brof you have good damage output.
Crit tanker and burster are harder to play considering the profusion of snipers and bonehead isnt enough to protect you.
After you can mix those builds but youll need to sacrifice crit chance/ special points .
