I think it’s a mixed bag. The new show is OK but I would probably read the manga first if you’ve seen the 90s show but read the manga yet.

This is basically “yet another take on Trigun” so it shares elements of both the old anime and the manga (Trigun + Trigun Maximum) but remixes it.

I think the direction could be better and the music isn’t as good as the original show, but it’s fun if you go in with the right expectations.
