I have many gloves, but the best ones I've ever bought are Sugoi SomethingOrOthers. They are pretty light weight, so fine with Ergos (or inferior equivalents) and they are super warm and waterproofing is good. They are way too toasty for anything above about 5 degrees (for me at least), but great for really cold weather.
I've had quite a few pairs of Specialized gloves in the past, but I just feel the quality has dropped in the last 10 years or so. They seem to fall apart very quickly...
