In my opinion, the strongest of the four is Thanos, due to his immense strength, durability, and the power of the Infinity Gauntlet.

Lastly, I would rank Wanda as the fourth strongest, as she possesses powerful reality-warping abilities, but may not have the same level of physical strength as the others. **
