I would go for the 10-24. I travelled with this lens and there were many times when I was very glad I had that 24mm long end. Also, there was a couple of times, when 14mm just wouldn't be wide enough.
Another thing is OIS can be useful sometimes. When I travelled to Rome with my Nikon I was very very glad I had OIS, because I found myself shooting a lot handheld at night or in dark places (dungeons, churches, etc)
