One thing to keep in mind is that AA has soft-landing, so, even if you don't make any status next year, you will still only drop to PLAT (and then GLD after that).
A viable option would be to go for UA 1K, and just enjoy the free soft-landing to PLAT on AA. UA 1K + AA PLAT may work out better than AA EXP + UA nobody (even though I personally feel that top-tier on AA is better than on UA, between the 2 extra SWU and the lack of fare class restriction in using them).
