Nope, Sapiens are still considered to be smarter by science. Neanderthals had a large brain similar to humans, but several vital parts such as the Prefrontal Cortex are much smaller while the Visual Cortex is larger in their brains, leaving them much less intelligent then Sapiens.

So basically they were more perceptive and better hunters. But worse planners, builders, educators, and less able to create large functioning societies like tribes.
