Celestial Mage or Celestial Line Rider? Rifter 10

[Malleable]

So I'm looking at the Celestial Mage and Celestial Line Rider from Rifter 10. Both are very similar, having access to normal invocations and Space magic.
The Mage has a few spells chosen, and 14 total. Slightly lower level restrictions on choosing spells at the start. Slightly less starting PPE. And the description says they can travel to other planets without the need of a spaceship...
AND they get Celestial Trance that gives insight into something with a successful Astrology roll. That seems nice.

The Line Rider gets 15 spells to start with higher level restrictions at the start. Slightly more PPE.
AND the more standard Read/Sense Ley Lines. Plus Ley Line Flight and Phasing.

Am I missing something? Any thoughts on which is better?

Thanks,
Mal
