I am wondering if anybody can shed some thoughts as to the best A32X implementation for FSX on the market now. I am by no means wanting to start a flame war, but I find it hard to compare products by the sales pitches you find on the respective producers sites. I long ago tried PSS and also the A320 from the guys that made Active Camera. I recently read about AirlinerXP, but that project seems somewhat dead.

If I am aiming for realism, completeness of systems etc., what should I go for?
