I'm fortunate to have the coin where it doesn't matter to me. For me it's about convenience of location. I have to "hit and run" with no real ability nor desire to book in advance, due to business constraints. Therefore I keep a roster of personal stock, AMP's, high-end asian places and asian individual providers in strategic locations around the city. I only bang asians (and i'm fing married to one!)
Right now the APC location is very close to a few active clients, and I've had good success there with quick calls. I've done HGITC, the sister spot, and will in the future. I really haven't seen much difference in the 350-400 range. I just had an awesome session with Bella at APC, she was as good as Olivia, a little less fun in the personality department, but very sexual, sweet tight coochie, all natural and licked my asshole clean and took a big load in her mouth after I banged her 6 ways to sundown, all for $350.
The reviews have not been so good on the other places you listed, at least on this board, and i've shyed away.
