"Best" for me might not be for you. I lug around a DSLR with one or two lenses, perhaps three lenses and a tripod. If you don't mind lugging around a substantial camera, then look to Canon, Nikon, Pentax, or Sony for either DSLR or mirrorless cameras.
If you want something pocket sized, then I'll recommend a 1" sensor camera. Canon, Lumix, and Sony have 1" sensor cameras that have pretty good technical performance and allow full manual control of exposure with decent ergonomics. The original Sony RX100 can be had for under $400. When I don't want to lug around my DSLR, I'll take the RX100 which fits in my pocket.
As others have stated, having a good camera ensures that you can get good technical results if you know how to operate said tool. Having a good camera doesn't mean you'll get good shots. Getting good shots is something that the photographer does with understanding of composition, lighting, styling, and understanding some technical details. It takes time and a concerted effort to learn all these things.
