That is a good question! When it comes to the Hulk, they were always wishy-washy on his mental capacity until the 1970s when they made him a dumb brute. The way the handbooks explain it, at least as far as the early green Hulk stories circa onward, was that the green Hulk was kind of had the grey Hulk's mentality at the time but that eventually faded away. Later on, when he used the gamma activator to turn into the Hulk, he was partially Hulk, partially Banner.

As far as Planet Skaar, I believe his intelligence there was due to exposure to the wormhole he passed through to get there.

The thing about the Hulk is that his mentality has always been like a psychological soup. The inconsistencies are usually explained away by whatever triggered his transformation, what Banner's psychological state was at the time, how much radiation he may have absorbed (if that was a trigger) that caused him to turn into the Hulk.

At the end of the day, the Hulk has always been inconsistent in mentality, intelligence, speaking ability. The only versions of the Hulk that were ever consistent were the grey Hulk and the Professor. I think the best explanation of this was from Incredible Hulk Vol 2 where they explained that Banner's mind is so fractured that every incarnation of the Hulk is a different personality. There are some versions that come out more frequently, but there are variants the pop up from time to time.
