Pros & Cons
Mural
Pros
- Facilitation features and LUMA frameworks make it strong for running structured workshops.
- Free visitors can view or edit individual murals, so external participants do not need a paid seat.
- Enterprise security includes SOC 2 Type 2, ISO 27001, SCIM, audit logs, data residency and BYOK.
- Broad integrations with Teams, Zoom, Jira, Azure DevOps, Asana and Confluence.
- Reviewers on G2 and Capterra rate it highly for ease of use, with about 4.5 to 4.6 stars.
Cons
- It is not a project or task manager, so there are no Gantt charts, no time tracking and no task assignment.
- Reviewers complain that menus and functions move around often between releases.
- The Free plan caps editable murals at three.
- The Business plan is annual-only, and SSO is not available on cheaper tiers.
- Large boards with many collaborators can feel cluttered.
Sierra
Pros
- Outcome-based billing means customers usually pay only for resolved conversations or other agreed results, not for each seat.
- Three build options cover both CX teams and engineers: the no-code Agent Studio, the code-first Agent SDK, and Ghostwriter for building agents from SOPs.
- One agent runs across chat, voice, SMS, WhatsApp, email and ChatGPT, keeping context between channels.
- Its list of compliance attestations is broad, covering SOC 2, ISO 27001, ISO 42001, HIPAA, PCI DSS and FedRAMP.
- It has a strong roster of enterprise customers, including SiriusXM, ADT, Rocket Mortgage and SoFi.
Cons
- There is no public pricing, and competitor estimates put annual contracts at about $150,000 or more.
- There is no self-serve or trial tier, so small teams cannot try it on their own.
- Implementation is largely vendor-led, which can make customers depend on Sierra's team for changes.
- There are few public reviews (7 on Gartner Peer Insights) to verify claims against.
- Some reviewers say voice quality still falls short of human level, and that complex telephony setups depend on how far the integration goes.
