Which is the best camera i can get?

I've been looking for a camera and doing some research but I need some help… I'm not a photographer but I'm thinking in studying it and i want to take pics as professional as possible with a camera that is not a DSR because i really cant afford it now… so in my price range i find this options… which one is the better?
Nikon Coolpix P950 or 510
Canon Powershot SX500
Sony Cyber-Shot DSC-H200 Digital Camera (i dont like the kind of battery it has but it's 20.1 megapixels!!!)
I will appreciate other suggestions… Thanks a lot !!!
