EPG Recommendation

Hi, I'm looking for an alternative EPG source and I know there are few out there such as xtream, iptv-epg, etc.. Please recommend based on experience which one of these services has the least down time and most accurate info to populate on tivimate/pp. i know xtream is a famous one but it seems the setup process is very time consuming and complicated would be nice to share any manual or guide available for it. Thx
