Depends on the flight. On long haul I sometimes go for window (if it's a sleeping flight), sometimes go for the aisle (if it's a working flight). The latter allows me to get up and stretch my legs. Daytime flights from Europe to Africa though I choose a window - never get tired of staring across the Sahara.
What annoys me is people who close the blinds on the non-sun side of the plane. 7 hour flight from Frankfurt to Lagos for example, Flight takes off about 10:00 (GMT+1), lands at 1800 (GMT+2). What possible reason is there to want to sleep on such a flight - very few will be transferring from outside Europe, and those that do are likely from the US, where they'll have slept on the previous leg.
On wide bodies, it could be a 2-3-2 layout, I go for the aisle on the middle in the hope that the middle of the 3 will be empty, or it will be a couple who won't disturb me. On a 2-4-2 again aisle in middle.
On shorthaul flights though it's always window -- no need to get out of your seat for a 2 or 3 hour flight, so board, sit, and not be disturbed.
