ERC20 on Ethereum VS “any other L2” – why?

I want to develop an ERC-20 token for a specific purpose. Initially, I’ve been strongly considering L2 like BASE or Polygon (low fees and fast transaction speeds), especially since my initial idea is to distribute tokens to a large number of addresses.

I’ve recently started thinking about launching on Ethereum itself. It is more expensive, but Ethereum offers a higher degree of decentralization, which could help my project appear more serious and credible in the long run.

What do you think? I know I will get biased answers, but I like it.
