Solana obviously is the best as we move ahead but we cannot take away Ethereum, the reason behind the success of Solana is the solution it has find to the problem of scalability, the 80% validation rules ensure the blockchain doesn't become centralized and behaves in a decentralized way, therefore, is absolutely secure, and the third best thing is the speed of transactions, it actually is the only blockchain which I can say can really be used as a medium of exchange because it takes less than a minute for Solana transaction to be confirmed which is really awesome. It did had a couple of outages this month, but if you deep dive into the reason of these outages you would realize these problems happened because of the inherent structure of Solana which keeps it quick, even though moving ahead devs should obviously try to reduce these outages. In terms of comparison with Ethereum, I think only time will tell, Ethereum 2.0 needs to come in time to compete with Solana otherwise it could easily take the lead.
