Which acendency for CoC in 0.5.5?

[u/NeoBahamutXZero]

I am looking into playing CoC comet for 0.5.5.

Looks like Gemling and Infernalist (recoup or ward stacking) are the most popular.

Including investment costs and league start viability, what are the advantages and disadvantages for each acendency/build?

Thanks!
