I haven't used an Anderson but I probably wouldn't get one fully assembled by them. Their reputation is too low.

Andro is apparently at least a step above. Although some reviews for the one PA sells for $400 every few months say that certain parts started rusting so I'd give it a once over with some gun oil right after I got it.

PSA's reputation isn't spotless but they in theory warranty everything they sell. I don't have any PSA stuff myself and I don't know how easy it is to get warranty service with them though.

The best values for a bulletproof AR-15 right now are probably the IWI Zion-15, if you can deal with its heavy barrel and handguard, or a BCM MK2 BFH Enhanced Lightweight Upper with free BCM bolt carrier group and the lower of your choosing. Both are going to be a lot more than ~$400 though.

I debating all of it. One thing I'm thinking too (at least to my knowledge) is if I get a full lower, I'll have to register it. I really would prefer not doing that. I could always buy something peer-to-peer. We'll see.

80% and a jig?

I think that's the ticket. Thanks for all of the advice homie.
