I personally use Real Debrid and can tell you confidently that with it your streaming experience will enhance dramatically.

Yes, you are more likely to find 4K or 1080 streams with Real Debrid than without. Since these links are less frequently scraped, they are faster to stream, offer buffer-free playback, and higher resolution links. The streaming links from these hosters can only be accessed if you have a Real Debrid subscription. Real Debrid supports more than 50 premium hosters. As a result, the free links experience heavy traffic and eventually cause slow loading and buffering issues. These links are available freely to everyone who is looking for them. Kodi addons scrape the web for the streaming links and line up the free ones for you to stream. Thankfully, almost all the addons support Real Debrid. This service can only be used on Kodi with an addon. Real Debrid is a multihoster that gives you access to the premium streaming hosters. You can configure and use Real Debrid through Kodi / apps on your FireStick, Fire TV, Fire Stick 4K, Android Tablets & Mobiles, iOS devices, Mac, Windows & Linux computers and more. In this tutorial, you will find the complete set of instructions to set up Real Debrid on Kodi and streaming apps.
