Familysearch is the best source. Unfortunately, I have noticed less original English records on entries, now. I suspect this is a move to encourage people to join FindmyPast.
As far as the US is concerned, it has original census sheets and lots more, whilst original English census records are licensed to paying concerns, so only transcripts are shown on Familysearch.

The App is incredible. I monitor it and report problems direct to the Developers and have had lots of Thank Yous from them.

I have changed or created over 46,000 Familysearch entries since 2022 and attached thousands of records and merged thousands of duplicates.

I am certain, if every researcher put their tree on Familysearch, corrected any errors and uploaded documents, photos and audio to their entries, most paysites would be forced to lower their fees.
