Cold vs Chaos Dot Spellslinger?

So Badger released his league starter idea with running Cold Dot Spellslinger (which you can turn into Big Bucks Self cast later) and it looks quite good.

Chaos Dot Spellslinger runs basically the same-way where you can league start with spellslinging and convert it into Self-cast endgame.

I was wondering for those who have played both version why would you pick one over the other? I was leaning towards Chaos because I played Self-Cast ED/CON before and its great, I never tried Cold-Dot before.
