For a build on a budget, PSA has a good albeit relatively new reputation for value priced, quality products. Their stuff hs all the right specs for great prices. I honestly think that they are going to be raising their prices again soon.
BCM has one of the greatest reps in the industry for quality products. You can't go wrong.
For a light use plinker/range rifle Id go with PSA.
For heavy use/home defence role I'd go with BCM.
