Is downsizing to better glass worth it?

[powds]

I’m thinking about upgrading my spotter glass from a gen 1 vortex razor 65mm to a swaro or Kowa but prices are wild these days so toying with the idea of going to a mini either the Kowa 55 or swaro ATC. I know the glass would be better but wondering if I’d be giving up a lot more in terms of zoom and FOV going smaller or if the upgrade in glass quality itself is worth it. I use it backpacking for the weight savings is nice and am looking to judge mule deer and identify goats, not necessarily looking to age sheep with it anytime soon

For me, 55mm spotter < 56mm binoculars. A lot.
