First R4 5* - Who to rank?

Colonaut123

So, I believe it is time to rank-up my first 5* to R4. I don't have the money yet, but by the time I've the last needed T4b I think I'll have enough. So far I had some pretty good pulls, but I have difficulties to choose. All are unawakened.

Roster from high to low
I've awakened 5/50 Blade, awakened 5/50 GR, unawakened 5/50 Stark Spidey, 5/50 sig 99 Red Hulk (no Masacre), awakened 5/50 Darkhawk (no NT), awakened 5/50 Sentinel, awakened 5/50 AA, awakened 5/50 Iceman, awakened 5/50 Mephisto, awakened 5/50 Killmonger and awakened 5/50 CAIW.
Several good 3/30 4* (ask) and 1/25 Red Hulk or 1/25 Ebony Maw (if buffed)
I've also 2/35 Gladiator Hulk and awakened 4/40 Gladiator Hulk, awakened 4/40 She-Hulk, awakened 4/40 Magik, awakened 4/40 Omega Red, 4/40 awakened Sabretooth, 4/40 Corvus, 2/35 Proxima, 2/35 Gwenpool, 4/40 Thing, awakened 4/40 Doctor Voodoo, sig 99 4/40 Storm, 2/35 Mordo, 2/35 Crossbones and awakened 2/35 Taskmaster

Interesting, why should I pick Domino over Blade?
