New to Sci-fi what's next?

Just finished this series and loved it, I haven't touched sci-fi before. I like the world-building and politics of Red Rising, but the action scenes are a little tedious for me probably because I smashed it out so quickly.

My Book Ranking: LB>MS>RR>GS>IG>DA (All were really good and I binged it, but I put IG and DA last because they paid off for me in LB).

Any recommendations? Ideally, a very different universe so I don't compare it to RR.
