omg it SO depends on my mood and what I'll be eating it with! cheddar is awesome on its own and in sandwhiches; but only if it's good and sharp. Same with swiss and pepperjack. mozzarella is only good FRESH in caprese salad or sprinkled w/salt and vinegar or olive oil (GOOD olive oil, none of that supermarket junk), and parmesan goes on salad and pasta.
bleu cheese is good in dressings, goat cheese is ok in moderation but it's a little strong for me so I like to put tiny bits in sauces for an added kick, and feta cheese is FABULOUS in omlettes and salads or even stuffed in olives; but it has to be FRENCH feta, not Greek feta; Greek has FAR too much salt for me, blech.
I'm not a fan of the softer cheese but the Hubbs just LOVES a good brie every now and then on some toasted artisan bread.
cheese is definitely one of the finer things in life, man.
