Is it a good idea to use CSS font-smoothing?

I'm working on a text heavy website and someone has advised me to go with antialiased font-smoothing mentioning that browsers add a solid color to the pixels in font glyphs while rendering which makes it look different(thicker) than how the designer intends it to be.

CSS font-smoothing property fixes this with implementation in webkit and mozilla with a considerably good support in major browsers (http://caniuse.com/#search=font-smoothing)

Is it a good idea to use CSS font-smoothing or should I just go with the default browser implementation?
