CGP are the best ones in my opinion, they have all you need to know to get a decent grade and all the notes you could possibly need to know for the specification. I literally revised using only the guides.
You can get ones with exam questions in them which are pretty good too.
Sciences and AQA subjects i would get CGP and maybe for the other subjects the Pearson Edexcel ones but either is good, if you're still unsure ask your teachers they'd recommend the good ones since they're probably selling them to the yr11's
