I use Northland personally
But jigs are jigs. Only difference really is weight, colour and the hook quality.
Get whatever ya can. I'd get some 1/4 and some 3/8 so so can fish shallow or deep. Obviously a 3/8 cast alot better and you can fish them shallow as well, you just need to speed up the retrieve.
For grubs I'd get 3", in black, white, chartruesse, etc just to have a variety. Any brand will do really.
