“Best” depends on your needs. If you take lots of short calls, prioritise comfort and an adjustable mic position. If your space is open-plan, look for a model that keeps your voice clear while reducing what colleagues hear in the background. An important tip: think about the room that you will spend most of the time using the headset. If you work in a busy room, you may require more isolation and comfort, to hear your audio, an over-ear headset can be a more suitable choice than ear-buds for example.
