With so many versions of oggenc floating around, i thought of putting together a list of some of them.

encoder: aoTuV beta 2
vendor : AO; aoTuV b2 [20040420]  (based on Xiph.Org's 1.0.1)
remarks: tuning done by aoyumi for all bitrates
aoyumi's encoders

encoder: aoTuV pre beta 2
vendor : AO; aoTuV b2 test [20040402]  (based on Xiph.Org's 1.0.1)
remarks: tuning done by aoyumi for all bitrates
aoyumi's encoders

encoder: aoTuV pre beta 2 + QK 3.2
vendor : AO; aoTuV b2 test [20040402]+QKTune beta 3.2  (based on Xiph.Org's 1.0.1)
remarks: merge of tuning by aoyumi and Quantum Knot (w/o HFR)
Quantum Knot's encoders

encoder: GT3b1
vendor : Xiph.Org/Sjeng.Org libVorbis I 20020717 (GTune 3, beta 1)
remarks: tunings by Garf for high bitrates (q >= 5), based on vorbis 1.0
Garf's encoder

encoder: GT3b2
vendor : Xiph.Org/Sjeng.Org libVorbis I 20031230 (GTune 3 beta 2)
remarks: tunings by Garf for high bitrates (q >= 5), based on vorbis 1.0.1
GT3b2 Encoder

encoder: GT3b2 + HFR
vendor : Xiph.Org/Sjeng.Org libVorbis I 20031230 (GTune 3 beta 2 with HF Reduction)
remarks: Garf's tuning merged with Quantum Knot's HFR
Quantum Knot's encoders

encoder: QKTune beta 3.2
vendor : Xiph.Org libVorbis I 20031230 (QKTune beta 3.2) EXPERIMENTAL
remarks: tuning for pre echo and high freq reduction by Quantum Knot
Quantum Knot's encoders

As of now it is recomended to use GT3b2 for encoding with q >= 5
For q <= 4 it is recomended to use aoTuV beta 2

Let me know if i missed some encoder or information is incorrect / inaccurate.

Nice.

You are missing Nyaochi's Modest Tuning:

This thread should be stickied.

Not sure about that, since some of these are just ment for testing and not recommendable for general usage yet.
I'd rather add more information to the Recommended Encoder Versions and Settings thread once some of the forks have 'stabelized' and are ready for general purpose usage.

rjamorim's test will hopefully produce some meaningful results.

I agree with devO I don't think all these experimental encoders should be sticky ... I think actually making listening tests in order to know if AOb2 is superior GT3b2 at all bitrate & in order to see if AOb2 should be the new overall HA recommended encoder would be much more clever than blindly adding every fork that exists ...

... not everyone even agree with GT3b2 being worth the bitrate jump so if all this forks get added that will become an even bigger mess ...

my personnal feeling is that V1.01 should be the recommended oggenc for newbies & AOb2 the recommended fork for advanced users (... with advanced earing)

The GT3b1 encoder also has Garf's "Floggy" tuning.  To enable it use files with 8KHz or 6KHz sample rates at q's -1 through -2 (yes, the Floggy tuning has a -2 q).  I've found that below q -1, mono files have very loud screeching artifacts while stereo files have no problems.
