Ash, by Mary Gentle- maybe a bit over-clever in places but it is fantastic.
Roger Zelazny’s Amber series… The first 5 in the series especially. It’d feel fresh and exciting if it came out today, never mind 40 years ago.
Already recommended … Joe Abercrombie is excellent- it does get a bit samey over time though- the same characters get used and used, sometimes with different names and faces. Definitely fits into the George RR Martin genre of “fantasy in which everyone is a dick”
Wheel of Time- yep, has good bits but they’re a bit drowned in the bad. Reading the Brandon Sanderson ones really does show up how badly Jordan had lost it. Not really sure I’d recommend it, too much of an investment in time. Radio edit required 😉
Speaking of Brandon Sanderson- again a little bit formulaic, it’s the same recipe every time- think of some interesting form of magic, write a story round it. But when it works, it works.
Haven’t read any Ray Feist for a while, I ended up not being able to tell which ones I’d read and which ones I hadn’t, they’re all basically the same. X of an angry Y. But the first few are excellent, as are the Janny Wurts crossovers.
