Thank you all for the insight! After another month plus of playing around with the different airlines and my normal destinations, it does appear I'll have to be spread out through all 3 alliances. That said my home airport being IAH, I will probably stop using my Chase Sapphire and get either a United Explorer or United Club Infinite card and try to boost my status with UA since my destinations can change over time but my home airport will probably be IAH for quite some time.
