This comparison was built from a structured review of official product documentation, published specifications, current pricing, and feature documentation — the same methodology ToolStep describes on the /how-we-test/ page. Because we did not run these products hands-on, we do not claim testing that did not happen.

Only if click noise bothers you or your coworkers. The shell, ergonomics, and scroll wheel are identical. If your MX Master 3 still works, keep it.
Logitech measures a 90% reduction in click noise. According to published specifications and product information, the 3S clicks are designed to be significantly quieter than the original 3.
For most users, no. The 4K sensor on the original MX Master 3 is already plenty for productivity. The 8K sensor helps on ultra-high-resolution 5K and 8K displays.
