I'm afraid SOL won't last for long if network outages persist. The inability of developers to provide a solution to the problem will make SOL go down the drain faster than you could've ever imagined. MATIC is a better option because of its focus on decentralization and censorship-resistance. It's a very underrated project simply because not many developers are working on it (aside from the lack of marketing/promotion). Solana is a different kind of blockchain with a different consensus mechanism, so people often find it a much more attractive investment than the former.
Ultimately, it comes down to which coin you'd want to invest for the long haul. As long as you do your own research before investing on a coin, you'll be on a road towards non-stop success. Who knows what the future holds for both projects? Just my opinion
