Why limit ourselves to one option when we can have both? I would say, save yourself a headache and invest in both of them. Besides these two cryptocurrency is very promising. It won't hurt if both give you a good profit.
I don't think Matic is over valued still up to this time, id indeed the market has already bottomed. Its time to buy loads of it. Once the tokens from ETH and BNB able to migrate to Matic and SOL, the two will have a good price.
These are all layer1 token, obviously they all have utility that creates demand when more projects are developed on its chain. The developers and projects contributes to rise of SOL or MATIC.
Matic in my opinion is still undervalued, comparing its price to other shit tokens that are more expensive. Besides Matic is already has a solid foundation and has been around the market for several years.
