The AdobeRGB has a wider possible range of colours, (you'll see this referred to a a gamut,) than sRGB, so AdobeRGB is superior.
However if you are posting to the web then you may as well use sRGB as that's the profile used in the internet. AdobeRGB profile pictures are automatically down converted to sRGB when posting to the internet, any colours that are out of the gamut will look odd and out of place. AdobeRGB and other wider gamuts are better for printing applications.
You may find that you can get better colour by using a Color Checker Passport.
You mentioned Faithful, which is a Canon picture style, the colours in your camera are processed to give a flatter look, I used to use it and applying a custom colour profile to bring the colours to a more natural, "as shot" look. Another way is to use the Standard Picture Style, which gives more richer blues and reds.
(This is the bit that may surprise, even though a photo is shot in RAW, the use of a picture style applies a colour bias to the RAW picture and in some cases such as the Standard Canon style, automatic in camera sharpening, whether you want it or not. I also used to use a custom picture style, based on the Standard Style with no sharpening being applied.)
