Like most aircraft, bulkheads here really just come down to how much legroom you need. I generally prefer bulkheads myself because you don't have to worry about anyone reclining into your space, but I'm not that tall so legroom isn't a huge issue for me. I grab everything I'll need out of my bag when I board and I'm good for the rest of the flight. On the A319 I wouldn't expect much disturbance from the galley given the types of routes they operate, and that's mostly only an issue if you're trying to sleep anyway.
