Sell me on your detachments

I have just about 900 pts worth of world eaters and from this point forward i would like to build into a detachment.

Currently i have
1x daemon prince (with or without wings)
1x Khârn the betrayer
1x MOE
1x Invocatus
10x jakhals
10x bezerkers
3x exalted eightbound

Its a pretty varied start so i want you guys to sell me on your main detatchment, bezerker warband is cool and all but i dont want to be limited to just that since the 1 pt detatchments look cool. KDK looks really cool and fun but im worried if too much of my army is bloodthirsters i wont have enough space for angron if i ever do get him, but if you guys can sell me on it or if KDK is doable without bloodthirsters i could very well be convinced. the one detachment i will most likely not do is cult of blood just due to me having tyranids so i have enough swarm units in my collection

Do your best to convert me to your chosen style :)
