I think that Etheruem and Solana are strong projects with great team, but presently, Etheruem still have an edge over Solana in term of stability, features, community, marketcap, and trading volumes.
Solana has been waxing very strong on it's network developments, we have been seeing new projects launched on it networks, though many are meme projects, but generally, Solana has great futures.
In conclusion, cryptocurrency is still evolving, anything can happen in future, Solana has the potential to dominate Etheruem, though it is difficult to predict the future of both token in my opinion.
