Every product has its hate, but everyone is rarely true. Personally (no longer at Amazon) I was impressed by Chime. It was simple, but rock solid, handling large calls well. Teams is still worse for me (>9 people display is bad, even in MS Edge, when on Linux). Zoom has a finicky interface.
Early in the pandemic I had to use many different systems as an academic, when lots of different contacts pivoted online in different ways. Chime was the least of my problems; it just worked when many other systems struggled.
I liked the Chime meeting/calendar integration at Amazon that could ring everyone at the start of the meeting, meaning that most meetings started promptly.
I was also at Amazon (AWS ProServe) we also hated Chime. AWS internally moved to Slack and only used Chime to schedule customer calls.
