ethereum - if you have a deep prior connection or you're someone like @ethereumJoseph, which I'll not adjectivize to keep this xeet pg solana - if the burden of choice is given to a real, serious, pragmatic engineer with half a brain tradfi rollup - if you get a grant, you don't really care about this crypto thing and just want to ride the current tech bros trend, or you've been around flat ethers too much and you got infected with the escape hatches brain worm other - if you want a bigger grant, aka build your own chain for no reason (there's a few exceptions to other right now, like choosing a good solana competitor, but those are exceptions and not the rule)
