Personally I don't really care too much. Let's take Kyber as an example. They have Vitalik as an advisor which bought them a lot of hype in the ICO stage but since then you really wouldn't have any idea that he was an advisor. Ultimately a project will be evaluated on the final release and an advisor won't have too much say or input in to this, they might help navigate a few situations but won't make a bad project in to a good one.
