Not technical, not scientific but after acquiring quite a few eyepieces andreading endless reviews in the end these are the ones I like the best and rank them.
Scope is an AP130GT:

1. APM XWA 9mm. (100 degree views are just wow. YMMV).
2. APM XWA 20mm.
3. APM 12.5mm Hi FW (close call between this and the 17.5 Morpheus, the APM just picks up faint stars that little bit better).
4. Baader Morpheus 17.5 (20mm eye relief and stable views with very little blackout plus sharp,good contrast and good throughput plus no barrel undercut which I have read endlessly are a pain, makes this series a winner).
5. 6.5, 9 and 12mm Morpheus.
6. Pentax XW 7 and 10mm.
7. Masuyama 10mm 85 degree.
8. Nagler 9 Type 1, Nagler 16 T5.
9. Edmunds Optics 28mm RKE.
10. APM 30mm UFF.
11. TV Delite 18.2mm

For narrower field of view but sharp:

12. TMB Planetary 11 9mm 56 degrees.
13. Fujiyama 18mm ortho
14. Edmunds Optics RKE 15,12mm, 8mm.

Barlows:

13. Baader Q extender
14. Tak 1.6X Q extender
15. Bintel 2 inch ED barlow.
16. Bintel quartx 2 inch diagonal.

What's yours?
