If you've got the money and can find them, the Edicion de Salvio is a world-class cigar.
The old ESV 1991 are among my favorite sticks (both natural and maduro), but they aren't made anymore and are getting difficult to find. But Perdomo just released their ESV 2002, which I've heard is similar, but I haven't had one yet.
The Champagne is one of the best mild cigars out there, imvho.
If you're looking for something cheaper, the Lot 23 (both natural and maduro) is one of the better cigars you can buy in that price range. Really tasty sticks!
As far as comparing Perdomo to EPC ... apples and oranges, imvho. Perodmo is all Nicaraguan (mostly Esteli), EPC are multi-country blends (typically DR and Nica). But the price ranges are similar, as are the levels of quality I think. Both make great cigars at affordable prices.
