Hard to tell.
The reality is that every mech combo does have advantage over another.
Now. if I will pick one mech that it is superior in overall functionality for the majority of things to do in the game
it will be the Heat hugger. That does not mean can't lose. It is a mech that can lose even with R7 mechs. It is a mech that can be use in full for portals, raid, farming, 1v1, 2v2, 3v3 pvp fights, war. Others mechs can do some but limited for other stuff.
For engines use premium combined items and phys. heat energy fortresses and plating. Torso MPV
