What;s your favorite current sat/B tool?

I've started using https://bitcoinfees.gitlab.io/ but was wondering if there are any other popular and accurate ones you guys like to use?

edit:
https://mempool.space/ looks even better

On another note, what explorer do you prefer?

I've been using https://blockstream.info not only because I like the company and their mission statement/what they do for the community.
But also really like the SegWit fee savings and Privacy analysis info it gives you.

I have not really looked for any other options in a few years so curious if there is a new favorite?

Thanks for your input!
