Personally, 
Hive has shown over the years that they have not taken the necessary steps to market, promote, and incentivize the developer community to build on its blockchain. Unfortunately, the writing is already on the wall.
There are much bigger players out there spending REAL MONEY to fight to become one of the top blockchains in the space. As Splinterlands has yet to launch their validators to fully decentralize their game, this is a perfect time to migrate the Splinterlands ecosystem to another blockchain that better values your community and their own blockchains growth.
Although HIVE may be better from a technical perspective, that often never results in a project becoming the winner. User experience and marketing trumps technical capabilities every time. Splinterlands is a game targeting mass adoption, and to effectively do that, the game needs to easily onboard non-crypto users via various methods such as account abstraction, greater Web3 accessibility, scalability, and mobile-first user experiences. Solana, Base, and even Polygon are focusing their efforts to meet these needs for their users and developers.
