What is the most comprehensive mod?

What is the best, most comprehensive, most enjoyable mod. One that has the most/best features, is reasonably balanced. Good for mid and late game? I have played floris A LOT. tried Brytenwalda- but map seems a bit small. Medieval conquest- spent 300 days building relations with a king, towns, opened productive enterprises, became a vasal and the country started wars, and got teared apart by rebels. Never tried medieval Japan mod, probably will start Nova aetas. Help please I'm in for a long run.
