Overall Polygon is a good choice for many but for NFT lovers SOL still has a good reputation.
I stopped using them a few months ago but Magic Eden is a good competitor to OpenSea.
People want low fees and fast TXs, but what use would that be if the blockchain in question is centralized? The only reason why SOL is in the top ranks in market cap it's because of the whales. There's so much money invested in this "shitcoin" that they won't let it go no matter what. FTX's collapse negatively affected SOL's price, but something bigger than that needs to happen for the cryptocurrency to die for good. Developers are already moving their NFTs to other platforms, so it should only be a matter of time before SOL becomes worthless.
Instead of Solana, why not consider Polygon (MATIC)? The latter is decentralized, censorship-resistant, and never had an outage since its inception (AFAIK). It could last a lifetime if it continues to succeed. Ultimately, the market will decide what will happen to SOL in the long run. As long as decentralization wins, nothing else matters. Just my thoughts
