I believe smaller champagne producers offer a more interesting flavor profile in their Non-Vintage blends. Some of the producers I like: Jacquesson, Pierre Peters, Gaston Chiquet, Larmandier, Egly-Ouriet and Billecart-Salmon. Not to say the big negociants of Veuve Cliquot, Moet e Chandon, Louis Roderer, etc.. don't produce any interesting champagne - they do but not until you get into the vintage and prestige cuvees. IMHO, of course. Frixenet is not technically champagne and should be compared to other sparkling wines outside of the Champagne designation.
