I somewhat agree. My favorite lightsaber fight is Anakin VS Obi Wan. But the Luke VS Vader ones come right next.
All the others come afterwards, with Vader VS Obi-Wan being dead last.
I'd probably rank them in this order
- Vader vs Luke in ROTJ
- Vader vs Luke in Empire
- Obi-Wan vs Anakin in ROTS
- Obi-Wan and Qui-Gon vs Darth Maul in TPM
- Obi-Wan vs Vader in SW
- General Grevious vs Obi-Wan in ROTS
- Obi-Wan and Anakin vs Count Dooku in AOTC
- Yoda vs The Emperor in ROTS
- Yoda vs Count Dooku in AOTC
