It depends for what you need the pictures. I preferred one with less pixels because I need my pictures mainly for posting on the web so I have to downsize them all the time anyway. If you have a big picture size they take longer to load, they take more space- you may even need a new computer to be able to work on them comfortably.

I would always go for a good optical zoom, more accurate focus and good light management.

Of course if you want pictures that can be printed (e.g. as a journalist) you need the pixels. I read that pixels can be a misleading information but I forgot why.

Or ask Jonza, I think he knows an awful lot about cameras.
