I highly reccomend not to buy any of the ACE weapons, and do not buy anything of NX. It looks like real bait, even though GP Permanents for NX are being sold for cheaper.

The highest total you can ever get up to 16,800 GP for one day for one specific game mode unless you make the set diverse.

Power grinding GP is best in Fireteam Cabin Fever, Black Lung, & Dead Water on Extreme Mode. You gain 1,000-2000 GP per full-clear near the top 3.
