Who to rank up?

I would like to go for skill mostly as I have some decent champions of other class.
But, exception may happen if others are really that great.
Who to rank up as my 5star ? Current level of these champs.
Aegon-awakened sig27 rank 3
Night thrasher- awakened so good 50 rank 3
Cull obsidian- awakened sig 20 rank 3
Corvus glaive- unawakened rank 2
Thabks for the help.
