I fed this table in ff123's analyzer :
MP3-V2 MP3-V3 MPC-q5 MGX-q5.5 MGX-q5.99 MGX-q6
2.00 1.50 3.00 2.00 2.00 3.20
1.50 1.00 4.00 2.90 2.90 3.50
3.00 2.50 2.80 3.00 3.30 4.00
3.00 2.00 4.00 2.00 2.00 2.30

3.00 1.80 3.80 2.20 2.40 3.00
1.50 1.20 3.50 1.80 2.30 3.40
1.50 2.70 4.00 2.00 2.00 2.30
3.00 2.80 4.20 1.60 1.50 3.00
3.00 2.30 4.00 2.30 2.50 3.50
I chose Anova, p=0.05, which gives

MP3-V2 0.792 0.119
MGX-q5.5 0.192
-----------------------------------------------------------------------
MPC-q5 is better than MGX-q6, MGX-q5.99, MP3-V2, MGX-q5.5, MP3-V3
MGX-q6 is better than MGX-q5.99, MP3-V2, MGX-q5.5, MP3-V3
Conclusion : if I understand properly the above, for Guruboolez' ears and samples, - MPC standard is the winner
- Vorbis Megamix -q6 is second
- All other are tied at third place.
