Is ERC20 expensive?

Excuse me, but could you clarify for me if ERC20 tokens are generally considered to be expensive? I've heard conflicting opinions on the matter, and I'm trying to understand if the cost of an ERC20 token is determined by specific factors, such as its popularity, utility, or the overall market conditions. Additionally, is there a standard range or benchmark that one can use to gauge the expense of an ERC20 token compared to others in the market? Thank you for your time and expertise on this matter.
