Opinions on the PS4 Slim vs the PS4 Pro

I am primarily a PC gamer, but am looking to pick up a ps4 for the exclusives and a change of pace from PC gaming. I now need to decided if I want the pro or not, is it worth it without a 4K TV the difference is $120 in Canada. I can afford the pro, but would rather use the money for more games if the differences in graphics are minor on my 1080p TV Thanks for any advice
