Sidi are quality for xc/racing, quite a small/ narrow fit though, my old sidi Dominators lasted years.
I wasn't impressed by the Look shoes I had, not the easiest to clip in and fell apart too quickly.
I currently have Spesh BG Comp shoes which are good, very comfy and clip in easily, only downsides are lack of studs/grip in thick mud, and they are made with very thin mesh material which is cool in summer but chilly on the feet otherwise, I invested in some Sealskinz socks for winter .
