Which Science champ should i invest in?

TB player, solo alliance, working my way toward paragon. Trying to figure out which of these science champs I should invest in for the longer haul? 6 stars are still relevant to me and i'm kinda slow to accumulate rank-up materials, so want to be smart about my choices and make sure i'm investing in champs who are relatively future-proof.

I included my 7* Hulk so you'd know why i'm not taking the 6* version up any further.

Photon or negative- they have a great synergy together. Photon has more utility yet negative has great regen reversal, counter and degen. Also; photon is photon

until they drop him as a 7, Torch is just a reliable solution to the entire spooky class.

you could (andI hope you do) luck out and pull either Silk or Photon as a 7. but Johnny is kinda like rMags and AA, a core staple for a reason. you will not regret spending resources on him.

Rank up human torch. He’s awesome, has so many uses, and isn’t a 7*. Silk is also a good rank up, but there’s a chance you pull a 7* version.
