Vintage Warmer is good. I'm not familar with the other thing you suggested. The LA2A brings a lot of big warmth for me to vocals. Either the real deal or the UAD-1 version. I was never a real fan of the BF version, but that works too. There's just a little more "cloud" in their plug-in for me. The distortion there, probably to help emulate the vintage compressor, is too much for me. The the UAD is Da' Bomb.
