MAX glory days are over, but I still want to have the MAX gameplay experience

I have not played MAX units before my investment in them was always close to zero, in hindsight kinda regretting it now as I try to enjoy every bit unique gameplay this game has to offer.

I have character of each faction, what are the max loadouts you will recommend? Given that you need to buy 2 weapons at the same time I want to buy the best ones first and see if I will like the gameplay
