I know which site you mean, and I have a sub to that, but for normal stuff, census etc. it's not particularly good. Sometimes you can find someone more easily than FindMyPast (in its old state) and Ancestry, but I checked today for someone I had already found on Ancestry and nothing came up. However, if you do find someone it will show the name, place of birth, relationship to head of household, (if in a census) occupation if an adult etc. so quite a lot of info before having to open the census itself.
For what it's worth, I'd stick with Ancestry if you have a sub for that. If you do subscribe as far as I can see renewal is automatic so you have to remember to cancel a sub at least 4 weeks before it's due. I've got a note on my laptop calendar to cancel my sub, so with that and FindMyPast, I'll be left just with Ancestry.
