I've enjoyed all the whites.
If you're asking about reds, I can't think of any I'd strongly recommend (WE had an Oregon Pinot Noir that was very good but no longer avail). I bought alot of the LEs. I will say the only RJS kit I tried--an LE Pinot Noir had KT too.
My favorite whites were a LE Chardonnay-Viognier, Estate Oregon Pinot Gris (after 2 years aging but it's no longer avail), Estate NZ Sauv Blanc and Estate Sonoma unwooded Chardonnay. I was also pleasantly surprised at the World Vineyard Trinity White for an early drinker (it's the only 10L kit I've tried). I age whites atleast 1 year, sometimes 2yrs but I ran out of ones ready to drink so I tried the small kit and it was good (not great but good for the price and I started drinking it after only 3 months aging)--Sauv Blanc style.
I haven't tasted any MM kits yet and my CC kits are all still aging.
