Actually during the pain fight he used his intelligence to outmaneuver the individual paths and used the intel he had on them to his advantage. Examples being how he used his clones and smoke bombs as feints and picked them off one by one and how he used sage mode to locate and track nagato down. Even during the third raikage fight he devised two separate attacks, the first one being a failure, and the second being a successful strike using his perceptive abilities to find a weak point nobody else figured out.
So... No. He has certainly shown a decent level of intelligence, but I can agree he doesn't show it consistently like when he fought edo nagato.
