I didn't find such a website that can see all the coins regarding their fees ,but I'm confused about it's for what ,comparing fees between one another because it also depend on the market because if I want another coin then I have to exchange the coin and it also drains a little fee at the time of exchange ! different cases if used in the long term AFAIK cheapest is xlm
It was expected that if the blockchain suffered from the congestion of the network, the fee could be possibly high and the transaction could be possible bit slow. So maybe Op comparing all blockchain status regarding their fees on which is reliable on making transaction and maybe anonymously.
It was given above as far as I know and that is a great tool that I even use, the blockchair.com is very reliable for that matter. If not, I recommend checking them every day.
