Venu 2 or Vivoactive 5?

It's my husband's birthday next week and I want to buy him a Garmin but don't know which to go for! He's a very active person (30k+ steps a day) and wants something to track his health in as much detail as possible.

Ideally it needs to:

- be able to display and answer calls

- receive WhatsApp and Gmail notifications

- be relatively hard-wearing due to his job

Which one should I go for? TIA!
