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.
I beg to differ regarding your point on no problems with the Polygon network. While Polygon Matic is the more promising of the two, there was a big outage on Polygon on March 10th and the chain halted. I just checked the groups and the latest status is that everything is back on line. A lot of people were worried over the weekend. In addition, there was recently a big performance impact on Polygon due to SFF. The network fees have gone up sharply on Polygon as well, although still negligible in comparison with Eth.
