Mice are 95% personal preference nowadays. Most companies produce good qualities, and what ergonomic qualities fit your hands are so individual that I cannot give you blanket advice.
RJN catalogues a lot of different ways to look at mice, finding things you find important, and ways to find mice that fit those categories.
It's how I ended up at my Razer Deathadder V3 Hyperspeed. I would recommend it, if your preferences were identical to mine.
