If you are interested in highest quality you should have a look at Garf's "oggencgt2". It is IMO better than the latest encoder at high bitrates (~160 and 350 kbit/s).
I can't comment on the 350kbps mode as I have never used it seriously. But I surely think that Vorbis 1.0 @ -q 5 provides better quality than Garf's 160kbps mode. I had a few samples that provoked really horrible HF artifacts in Garf's mode (one of which I remember posting here) - Vorbis 1.0 performs a lot better on these, even at -q 4 IIRC.

I can verify that Garf's GT2 modes did indeed perform quite a bit better on many samples than 1.0 at similar bitrates. Of course, I'm sure there are samples where 1.0 does better now because of other bugs being fixed (like what you mention), but for example, on many pre-echo inducing clips, Garf's modes were significantly better.
I was actually a bit surprised when I first tried 1.0 because it seemed like a general step backwards in quality to me. Not trying to start any flames here or anything, but I think a lot of this just has to do with the fact that Garf's Tuned modes where just that, highly tuned to provide the best quality within the limits of what Vorbis already provided. A lot of that was not carried over to 1.0 because of changes in code that made it not quite a simple task, according to what Garf has told me. So Vorbis 1.0 may be more
stable overall in regards to quality than what the GT2 modes did, but it doesn't seem to produce as high quality as GT2 most of the time, at least on most of the difficult samples I've tried both on.
This really just kind of underlines the issue that 1.0 needs to have it's higher bitrate settings retuned in the same manner as before.
