Personally I like to use gear and melds to get to the Craftsmanship requirement for recipes of the current patch (in the case of 2.4, this is 451 Craftsmanship), then max out Control anywhere you can with whatever options you have (likely just your offhand tool if you've hit 451 Craftsmanship) because let's face it.... everything but furniture in this game is "HQ or don't bother". For food, I would focus CP food for those super hard synths, and Control food for those synths you know you can do on your normal amount of CP, but want a boost in HQ chance for.

I hope that helps!
