Social Impact Token

So I've decided I'd like to start a social impact token. I've been doing some research the past few weeks, learning as much as I can about the best way to go about things to get some actual longevity out of the project. I'd like to build a solid community and attract the type of potential investors who would like to be part of something bigger than themselves, helping others and making some money doing it.

First and foremost, I'm curious what blockchains you guys prefer? I'm considering Ethereum and Solana or Binance Smart Chain. I know Eth has the more established chain and community, while Sol and BSC have faster transaction speeds and lower fees. I'm thinking a dual-chain and dual-purpose token is the route to take, I'd just like to know which ones you prefer?
