You should be focusing more on the games the platforms have to offer, rather than the specs of the consoles.
If you want games like Mario and Zelda then you'd want to go with Nintendo, but if you want games like Uncharted and Horizon, then the PS4 will be better for you.
When it comes to PS4 vs PS4 Pro, I would only recommend the Pro if you have a 4K TV and/or a PS VR (or plan to get a 4K TV/PS VR) Yeah you'll get slightly better frame rates with boost mode, but it isn't worth the extra cost just for that alone. Although the PS4 Pro can output at 4K, it doesn't have a 4K Blu-Ray player so for 4K video, you'll have to stream it.
In terms of actual spec, it goes PS4 Pro > PS4 > Wii U
