You'll buying into a system. Look at the whole picture and if you like it - financially too - give it a try.
You also have to like the ergonomics so a trip to a camera store could be helpful but I think one can be used to either of those in a few days. (including menu systems). I shot with Canon/Nikon/Oly no big deal. However the best would be some real life experience: Rent them for a weekend.
The other thing... and you might not going to like this angle
If you go to a page like 500pc youpick fotozz.hu photoshop.com viewbug.com etc. etc..
You'll see a load of amazing images and without the info next to them (with a small exception) I doubt anyone could tell what cam/lens they used. Both of those are great and you can use them for pretty much any type of photography.
So bottom line is that it's YOU behind the camera that will make those great images.
..but if you want an unbiased opinion pick Canon
