If you enjoyed Sillage, Morvan did a lot of other sci-fi works. HK comes to mind. Meka too.
UW1 & 2 are quite good (relatively grounded, band of people in the fulcrum of a major event)
The Fourth Power, if only for Gimenez's art.
Yoko Tsuno is a classic (episodic adventurer ala Spirou). As are bds by Bilal or Jodorowsky, but they're a bit hit or miss.
Leo did his Kenya/aldebaran/betelgeuse series. I'm not a fan, but I'll admit they are solid works (alien exploration). Same for Kookaburra by Crisse, in a different style (space opera).
Shangri La if you want an original one-shot (politico-social troubles in a space station)
Womoks by Boulet & Reno (seen in the last Aquablue issues) is one of my favorite funny comics (military squad hijinks)
If have nice memories of Babel as a kid, and I generally like Ange's stuff. (guy recruted by space customs)
Heard very good things about Gipsy, but haven't got around reading it so far.
