With the 10k bonus, the earnings rate ends up being 1.4 miles/$ for the first $25k spend. So after that I generally switch to Freedom Unlimited for 1.5 Chase points / $ (have a CSR pairing) for general spend.
On that note, I've been paying rent with my card, which helps me meet spend on the card without resorting to VGCs. Landlord charges 2.2%, and given the 1.5% valuation of UA miles, it ends up being an extra 0.1% for the fee, or $25, for the whole spend.
