Blanton's is terribly difficult to find. To be completely honest, it is not as good as Eagle Rare in my opinion. My favorites are Eagle Rare, Blanton's, Angel's Envy, Buffalo Trace, and Old Forrester 1920. There are tons of great whiskey, it just depends on your budget and palate. For everyday consumption, I would recommend Jefferson's, 1792, Larceny, and Very Old Barton if you can find it.
People are into rye right now, so if you want the spicier side of life, look for Redemption, Sazerac, Templeton, Rittenhouse, and WhistlePig's Rye.
