If you have the money, get a pro. I don't have a 4k tv either (yet) and I got the PS4 pro because I figured why not, and I love it.
If money is an issue, you could buy a second hand PS4 or brand new slim. I'm sure by Black Friday they will be even more cheap than they are now.
I gave my OG PS4 to my room mate to use in the living room, while the Pro is in my room and she has an Xbox one in her room. Only reason I wanted a new PS4 in the first place was because mine was starting to show its age. I finally took it apart and cleaned it out, and it works just fine now. But I still got a pro and haven't looked back.
Hopefully by Black Friday those LG OLED 4k tvs will come down in price.
I believe there are 2tb drives available now too for PS4 consoles
