I just finished reading through one in
Star Trek Vanguard: Harbinger and cripes, it was tough. It's the same with reading a space battle in a Honor Harrington or Lost Fleet book, they're just more intense than what a show or movie normally offers. I think with the latter, there are elements missing, like what the characters involved are thinking, what's happening elsewhere other than a ship's bridge. I'm not saying that space battles in visual media aren't exciting, because they are, but there's just something more visceral, more personal when you're reading about a ship getting pounded and a favorite character of yours gets decapitated or sucked out into the void of space.
I can't recommend Harbinger highly enough. So good. So damn good.
