What are the best rechargeable batteries?

With the amount of electronic devices and gadgets I’ve got, I’ve practically become an expert in rechargeable battery technology and maintenance over the last few years, I even custom build my own LiPo packs for my RC toys. One thing I’ve always done is buy GP AAAs and AAs for my gadgets and cameras. I’ve got GPs that are at least five years old and are still used daily. The best thing about GPs is that they’re really cheap if you buy them from a Hong Kong seller.
