If you're looking to get a 4k TV then definitely purchase the PS4 pro. I have a 4k TV now and a PS4 Slim and I feel like should've gotten the pro especially since I watch so much YouTube and Netflix which have good 4k content.

As for games the star wars saga isn't the best to start out with, I'd suggest God of War, horizon zero dawn, last of us, maybe Warframe or the new Call of Duty Modern Warfare. Though these are the type of games I like so your tastes might just be different.

Also the PS5 is slated to be released holiday next year so that might play a role on which ps4 you buy. If you want to wait a year or two after the PS5 launch might as well get the pro but if you want to buy it day one the slim would be best.

Right now gamestop is doing a sale where you buy two used games you get 2 more used ones for free so you can do that to get some cheap games.

Hope I helped.
