Haven't read a lot of these.

I don't have Time for the Stars, but I read it many years ago. Not one of my favorites. Never read FitS or Rolling Stones.

I have the trilogy that Black Sun Rising starts. The three books are self-contained, so you're not committed ;<) . I enjoyed it.

I've read some of Weber, haven't been able to get into it.

I've enjoyed a lot of the Card I've read, but also got disenchanted with the last of the Ender series. But I haven't done much of the Alvin Maker.

Enjoy your journeys!
