There are the widely recognised and used Sage leaves that come in green, purple or variegated forms, all with the flavour you'll know and want for recipes and they do all taste the same - so choice is based on personal preference, the colour you want in your garden. There are also fruity Sages that are ready when the weather warms up; Blackcurrant, Pineapple and Tangerine sages all have scented leaves and striking flowers but are a little less hardy and lose their leaves over Winter so become available once they show signs of life again.
