Bought a Venu 3 and now an Epix gen 2 (Which to keep)

I've purchased a Venu 3 but awaiting a lengthy delivery time for it. I chose it over the Vivoactive 5 due to its further features.

A day later a deal came up for an Epix gen 2 standard edition for near the same price as I paid for the Venu 3 (Venu 3 £349, Epix gen 2 - £375). Now I'm a little unsure which to keep.

If I keep the Epix gen 2:

- I'll lose the Elevate 5 HR sensor (A big issue?)

- Will I lose picture view in text messages that the Venu 3 has or has a software update added this to the Epix?

- Lose the slimmer/smaller design of the watch.

- Better battery life.

- Greater depth of metrics

If I keep the Venu 3:

- Keep the picture text message alerts.

- Ability to answer calls on the watch. (not too worried about this)

- More compact watch

Any other major differences I would be giving up? Worth asking on the Epix gen 2 forum?
