Tony Northrup has a great video about how much difference it makes in postprocessing whether you have shot your photos in RAW format or in JPEG. It's just crazy how much additional information you can get out of the same shot using RAW. Also, you get much more flexibility during the shot, when you don't have to fiddle around the WB. He also points out the negative parts of RAW which are basically that they need more space on your HDD and the buffer for serial exposures runs full much faster. Which can also be a blessing afterwards in postprocessing...where finding THE ONE in 10 almost identical pictures is already really annoying.
So for everyone who's thinking about taking shots and get as much as possible out of them afterwards RAW is definitely the go-to format, despite their much bigger file size!
