To me it's a matter of just how much less leg room. On an A320 on the A/C side I find the bulkhead row sucks however on a A319, there's lots of leg room on the A/C side bulkhead.
I ended up taking 1C for a seat swapper. Noticed that in 1D the IFE screen is centered on the seat, in 1C it's offset. Leg room was acceptable for me, but I'm more like 5'9.
