my choice is polygon, for all the time of use there are no problems with the network, transactions are fast and most importantly cheap, but the solana network has hung up several times and this is a big minus today, this project occupies the top 10 CMC and should work without failures.
What do you mean Solana network has hung up several times, i have not encountered that situation. When it comes to investment, i will go to Matic aka Polygon because of the use case and the really low valuation and on the other hand Solana had its rally and majority of the projects that uses ETH network as their base platform usually migrate to Polygon because of the ease of migration and i always felt it is undervalued.
