They're both slow at the bottom. You'll probably upgrade faster at PSA. Just keep your apps out everywhere, and head to PSA. If AA isn't your only goal, then you can probably be out sooner than the nine years to flow.
Specifically to the OP: if you can get back in at PSA, then definitely do that. If you can't, then 9E probably will treat you better than YV if you're up for another 121 initial stint.
