I mean, they weren't LoTR-level, but they were still enjoyable. Wheel of Time ending and Stormlight 1/2 may still be his best works, but the Alloy of Law stuff was still solid, at least in my opinion.
His B-reel books are usually decent ideas, but you can tell when it's Brandon's voice leaking through the characters instead of the characters themselves. He tends to take a bit more care of his larger, mainline books.
I'm a big fan of the Stormlight Archive where all main characters have some form of mental disorder. That said the last book was getting a bit repetitive, always waiting for the same character to snap out of his seasonal depression in order to save everyone just in time. I'm still a fan, I even watched some of his lectures on creative writing but there is definitely a formula to how he works.
Not OP, but it felt less polished to me than his others. Part of it was also that he was intentionally tweaking his style for the series (inspired by pulp Westerns). No dramatic difference, but enough to be slightly off.
