I agree because way back 2017, almost everyday there is a new coin listed on CMC including shitcoins which I think the reason why CMC raise its standard for listing new coins. Coingecko is not new but competing with CMC's popularity is one of the possible reason why they accept new coin easily and one more thing is they want to get more traffic on their site due to the people searching for the new coin.
CMC don't wanna let some not useful coin to be listed in their platforms, so expect it to be fewer than coingecko. In addition, I do trust both of these but I used to be in CMC than coingecko for safe purposes I guess or for validation of my thoughts whether the coin is shit or not. Maybe you soon be realizing how reliable CMC than coingecko although they are both good.
