Thanos has said himself he wouldn't want to get into a brawl with the Hulk. I know that he was probably talking about Savage, but still Prof. Hulk is stronger at base, plus he is smarter then you add Immortal Hercules who h2h is one of the best of the powerhouses, and I think they might be able to take a few away from Thanos.
The professor starts at a higher base strength than the regular Hulk, but cannot amp up as quickly, which is going to count against him because Thanos is going to come out hitting hard right off the bat.
Thanos used to be class 100 before he enhanced himself with bionics, then when he was resurrected by Death he gained even more strength than he did when he was enhanced. To top it off he can augment his strength with cosmic energy, making him immensely strong and durable right off the bat without needing to amp up.
This is why he can easily smack around the Hulk and take hits from Thor enhanced with the power gem in warrior madness.
For Herc to stand a chance, he would need the power gem or some other plot device, he is not overpowering Thanos, no chance in hell, and the only version of Hulk who would stand a chance is savage hulk.

I still haven't seen Thanos use real fighting skills though. In fact, I haven't seen him use one move or attack that Hercules or Hulk can't do either.
Thanos' fighting skills are slowly moving towards his victim and beating the crap out of him 😆
