Can't argue with that. I like the SAS / Air Canada / *A lounge in T3 as well - very spacious (2 levels) compared to BA's offerings. The KLM Holideck in T4 has a good reputation as well, but I've never used that.
Obviously the worst lounge (and I include the Servisair lounges in this comparison) is the LH / *A lounge in T2.
