I admit I was really impressed with how useful I found Fizban’s - I only hesitated on Bigby’s because I’ve never found giants terribly compelling as adversaries. A book that could make them compelling would be very cool, actually.I hesitate to recommend any books as people have different wants and tastes. But for me, it is one of the best 5e books. I would follow @Parmandur's suggestion and try to flip through it a bookstore or library to see if it is for you.
