AMW,
Fold 3 is ONLY military records. I subscribe to both FindMyPast & Ancestry at World level and find myself using FMP rather more than Ancestry. I frequently go to Ancestry for images of parish records, because FMP quite often has only the transcription, but it is really a matter of horses for courses! One useful free site is forebears.io, simply because it is a list of links to parish registers and other records, both free and paid for, with the years that they span. If what you want is not on their list, then you can be pretty sure that it is not online.
FMP also has an extensive collection of UK military records covering those that have survived from WW! and earlier Boer War and militia records. I have no experiemce of subscribing to The Genealogist, but I am occasionally linked to there from forebears.io for some particular parish register.
Don't forget to try the freebies such as FreeBMD, FreeReg, FreeCen, and familysearch.org. And if using the latter, don't forget to search their catalogue. Their main vaults in Salt Lake City contain films of all the parish chest records such as Poor Law records, which contain pre-1837 information that is not available anywhere else other than perhaps county archives. You can order up copies of some of these films to view at their LDS Family History Centre at 38-42 Lordswood Road, Harborne, details here:-
https://www.familysearch.org/wiki/en/Harborne_England_Family_History_Centre and there are various other centres dotted around the UK and overseas. Films not in stock can be obtained within 2 to 3 weeks and you then have 6 weeks in which to view them as often as you like. The staff are all volunteers and very friendly, and won't attempt to talk to you about their particular brand of religion. All my years of early research 30 years ago made extensive use of their Centre in Poole, Dorset. When the LDS Church originally sought permission to film UK parish registers many years ago, it was granted on the condition that they made access to the records available to all, whatever their beliefs and non-beliefs, and this condition is strictly adhered to. There is a lot more information here:-
https://www.familysearch.org/wiki/en/Introduction_to_Family_History_Centers and one interesting thing I note is that, like some libraries, you can obtain free access to Ancestry, FMP, British Newspaper Archive, and others from the PCs on their premises.
Finally, please make use of this Forum as members will always help if they can. Sorry if this is a long reply, but I wanted to add some information about resources that otherwise rarely get mentioned.
