I have been using Briess for the past couple of years, as that is what the LHBS stocks. While I had issues with Briess in the past (like, 14-15 years ago), I have had no problems with it now converting and/or leaving a nice malt flavor in the IPAs I brew, which is the only style I use it for as a base malt. I go through a lot more Continental pilsner malt than American pale.
I do miss the MaltEurop that the previous now defunct LHBS kept in stock. I thought it was nearly equal to Golden Promise.
My issues long ago with Briess were more due to the drought that we were experiencing here in the malt growing heartland. The kernels were real small, and I got horrible efficiency. At that time I switch to British Columbia malt (Gambrinus) which did not seem so affected by the drought.
