Nikon l180 16mp or fujifilm finepix s4300?

I'm doing a gcse photography class and am getting a new camera. I'm stuck on which to get, they're both similar prices. With the Nikon camera I noticed there is no eye viewfinder like the finepix, it's just an LCD screen, is this harder to use or easier?
Thanks

What waterproof camera would be best for use in a cold creek?

I was wanting to take some underwater pictures in my creek next summer, it's pretty cold in it- never warmer than 50 degrees. The deepest part is 7 feet, the water is a little murky, but not awful.
A good waterproof camera that won't break easily would be perfect! I was looking at a Nikon Coolpix AW100, but apparently the seal on them is no good… ? So I'm not sure now… what would you reccomend?
