Andy Serkins also narrated Lord of the rings and the hobbit. So that’s a place to start too. Personally I think Marc Thompson is great. He narrates tons of Star Wars audiobooks, if that’s interesting for you.
I have a hard time recommending a specific narrator, as it (for me) totally depends on the book.
the narrator make a big difference to me too. While I haven't listened to this narrator in particular, I really enjoyed these productions lately on audible
Dune - has multiple voice actors
Star Wars: Heir To The Empire - happens after the orig trilogy, really good voice actor and also has some sound effects
The wheel of time: Eye of the world - Michael Kramer narrated really well here.
To Sleep in a Sea of Stars - Story itself was really captivating. Narrator Jennifer Hale was also fantastic
Project hail Mary audiobook has great narrator IMO.
Almost anything by Ray Porter is incredibly well read and well produced. NOS4A2 read by Kate Mulgrew is solid.
I haven't heard this Silmarillion, but I really enjoyed The Expanse narrated by Jefferson Mays.
I really liked the narration of The Adventures of Amina al-Sirafi. Two narrators actually, one who does the first person narration of Amina which accounts for the majority of the story, and one other narrator serving as a story teller filling in narrative details, letters that appeared between chapters, and that sort of thing.
The narrators felt like they were part of the world the book describes, and Amina's parts in particular are told as though she's recounting her story at a tavern (complete with occasionally turning away to shout at a particularly obtuse listener). In short, it feels exactly like you're listening to the pirate captain recounting her own tale.
Have listened to most of the ‘Cradle’ series by Will Wight, narrated by Travis Baldree. He does an excellent job.
Project Hail Mary read by Ray Porter is amazing!
Others have given great suggestions for good narrators but I just want to add that audiobooks work best for me when I'm doing something else to keep busy. I have a job that doesn't require much brain power or interacting with people so I can use earbuds at work and that's my favorite time to listen to audiobooks, I got through the three body problem in 2 days and over the last 2 days I've gotten 3/4 of the way through the second book. I've also gone through the whole series of The Expanse on audiobook as well.
Give em a shot when you're doing tedious chores or out for a walk, or at work if you have a job that allows it. I've heard of others that like listening to audiobooks while driving but I've never done that. I've tried listening to audiobooks without doing anything else and my mind wanders to much, and if I try to read along with a book in my hands then I tend to read to fast to keep up with the narration and it just ends up being a distraction.
I think anything narrated by Julia Whelan is great. She has a beautiful voice, and does an amazing job of making each character have a unique voice. Both male and female characters which a lot of audio book narrators struggle with. It’s really impressive.
