Ethereum without a doubt.
It's not about being the favorite actually, it's just about relying on what it will bring in the future, money-wise. It's the top altcoin for a reason and because of that many investors will keep on going back to Ethereum and purchase it making the demand soar to a number that is unexpected.
Just like now, it's back to Over $2000 again and it will keep on rising while the best cryptocurrency is also going up. Bitcoin.
I think that Ethereum will always be the wiser choice when it comes to investing in cryptocurrency and we should stop wasting time looking for a gem that is like a needle in the haystack. It's a waste of time, money, and effort, we will just keep on hurting our wallets by buying different coins that won't really give something back in the future.
Ethereum on the other hand, just needs patience because it's going upwards no matter what. There will be dumps because it's part of how the market behaves but it's still going up after that.
ETH has always been the second best alternative coin after Bitcoin to invest because they really have benefits that can make everyone benefit each cycle, apart from what you express the other few sentiments from the development of ETH is also planned to make the same ETF submission as Bitcoin ETF , of course this will be a bullish sentiment for the development of ETH prices in the future with its advanced technology.
From the list it is ETH and Polygon. ETH for being more resilient with its adoption and user growth. There were some projects that had community support but they failed to keep that community intact. That community splintered in several other project and the original project lost its cause. ETH shows its performance, growth and adoptive nature in any market demand.
Polygon I like industrial-grade highly scalable blockchains. It has a massive community, low gas fees and support from the main ethereum community. The most important part is that they have the support of big companies that they have partnerships with.
I also like polygon because they do a pretty good development for scalability and transaction costs, as well as other things they update for the development of their ecosystems, I have heard that polygon/matic will change its name to pol with the latest proposal in which there is an integration of progress Polygon network.
