There are different pros and cons for both headsets.
Why I would choose the the Vive Focus 3:
* No hard binding to a company - you just buy a headset and do not have to connect you to a social media platform - very important in business context
* Better of the shelve comfort - the standard head strap of the Vive is very comfortable and the weight is better balanced
* Exchangeable battery - I think this is a big advantage for various usage scenarios
Why I would buy the Quest 2:
* Cheap headset with no problem with Facebook binding
* Already more content in the store - more development is going on
* Larger sweet spot and less god-rays - in most use cases I have no problem with it
* No fan - for some applications of the Focus 3 the fan is a bit disturbing
* AR Mode - pretty knew for the Quest but will get interesting
Privately I would always choose a Quest 2 as it offers more for a small budget... However in business context I personally would recommend the Vive Focus 3 as you have less problems with privacy.
