Which one is a better deal?

Depends on what you need. Axiom: Axiom sits in the lean/self-serve middle of the observability pricing pack — not a loss-leader like some free-forever tools, but far cheaper to start than enterprise-gated competitors that force you into a sales call for basic controls. They're clearly going after teams that want enterprise features without the enterprise sales cycle. Datadog: At $18-27/host, Datadog sits firmly in the premium tier of observability — more expensive than open-source stacks like Grafana + Prometheus, and pricier than New Relic's per-user model for many team sizes. They're not chasing budget buyers; they're targeting mid-market and enterprise engineering orgs that want a single pane of glass and are willing to pay for it.
