Basically what HandicapdHippo said.
There have been mayn threads about which of the two mods does what, or which one is "better", but in the end they are both really good choices.
HIP is more modular than CK2Plus for sure, and it has a fancier map with a (you could call it "pedantic"

) focus on historical accuracy. Plus has a redone map as well, but over here everything is more focused on giving balanced gameplay options than being historically accurate. That's probably the main reason I stayed with Plus, because I value gameplay fun more than historical plausibility.
But that depends on one's personal preferences, of course.
EMF has shaped up pretty well lately, so I guess HIP is also more "fun" to play right now than it was. But both mods are ever still gaining momentum, with Plus recently adding flavour to heresies, in addition to the flavour the old religions already got (we have Celtic, Hellenic and Kemetism).
The faction system of Plus is
way superior than anthing else out there, while HIP has VIET, which brings a lot of new random events (90% of them are about baklava or xwedodah, but oh well...

).
More features to list I don't have time, but I guess you see both have their strengths, and a slightly different focus.
Anyway, if the new HIP comes out and I get permission, I will once again bring CPR and VIET as submods for CK2Plus. Because, tbh, I can't play without parts of HIP now as well.
Thankfully we have both mods
