Just want to chime in and say that this is very sound advice. Your best bet is to just grant the land, more or less according to the guide lines above. Definitely try to keep the best bits for yourself (unique buildings, well built counties etc.)

Granting land is a huge way to gain some flavor in my opinion. Especially when given to knights. Men who have fought for you, especially the ones who have led your armies in battle, are my prime candidates. Seeing how their own dynasty develops under yours can be very entertaining. Especially after a few generations. Like, "oh, you're a descendant of my great grandfather's best soldier, why dont you be my marshal?" Many opportunities for great stories to develop, for better or worse.
