reed has the power gem and warlock at his side as a guide. thay could simply give it to classic strange who could then invoke demons that he couldn't handle before, but will be able to with the power gem fueling his magic.
plus warlock defeated all of strange's most powerful books simultaniously with only the power gem, so the power gem is indeed more powerful than classic strange.
Team Two, pretty easily IMO.
Thanos has the best tech on the field.
Zemo's moonstones provide him with infinite power.
Doom has intimate knowledge of how Reed operates and is capable of countering anything he would think up.
Hell, Thanos' tech is so incredible he's come up with a functioning copy of the Reality Gem, as well as draining the six infinity gems to create another, Star Gem.
