CCR2004-1G-12S+2XS vs CCR2116-12G-4S+ for a colo IPv6 edge, Feedback and Suggestions needed.

Planning a colo deployment and leaning toward the CCR2004-1G-12S+2XS.

My goal is to:

• Announce a few IPv6 prefixes via BGP to upstream(s)
• GRE, IPsec, and probably a few WireGuard tunnels out to remote/sites.
• Some remote sites get a dedicated delegated subnet, as a few sites simply either don't get IPv6 at all or its not static.

I've also eyed the CCR2116-12G-4S+ as the beefier option, but it's roughly double the price.

Anyone running a 2004 as an edge/tunnel-aggregation box in a colo?
Wondering how real IPsec / GRE-over-IPsec throughput per tunnel is in practice.
Is WireGuard on RouterOS v7 usable, or is it still the weak spot?
Any reason I'd actually regret not going 2116 for this?

Interested in feedback and cases.
