The project hasn't been able to deliver concrete results, other than being hyped up by its supporters. It's only been on the top because of the low fees and ultra-high performance. Considering that Solana has been a victim of several network disruptions, I don't think it's a blockchain to be "played with". People want something that's secure and reliable, not something that can go down periodically (like it's the case with Solana today). If network disruptions/outages keep up, I'm afraid SOL will go all the way down the drain at a very fast pace. Ethereum may be more expensive and slower to use than Solana, but it's safer and reliable than most projects out there in the crypto/Blockchain space.
The promises that they gave to people are really cool. I am not going to lie, if SOL team delivered on their promises then it would have been something marvelous and they would have been one of the top coins, probably reach at least third place.
However, as you have said they are not really delivering on their promises and that is the main problem. Not that there is anything wrong with what they have right now, their capabilities are fine, but they promised more and this causes problems when people force it. If they can fix it all and have a working product exactly as they hoped for, then it will not be full of hype, but for the time being, they do not have that and it looks like full of hype only.
