Pros & Cons
Cursor
Pros
- It is built on VS Code, so developers keep their extensions, themes and keybindings when they switch.
- Agents run in the IDE, CLI, cloud, web and mobile, and Cursor 2.0 added parallel agents.
- It holds ISO 27001 and ISO 42001 certifications plus a SOC 2 Type II attestation, and Privacy Mode is available on every plan.
- Enterprise admins can control repos, models, MCP servers and network access, and audit logs are included.
- At $8 a month, Plus is a low-cost entry point for individual developers.
Cons
- Reviewers often report unpredictable usage-based bills and contentious pricing changes.
- Included usage covers Grok models only, so Claude and GPT usage is billed extra at API rates.
- After the SpaceX acquisition, legacy plans closed, and switching to a new plan cannot be reversed.
- There is no self-hosted option, and some reviewers say cloud processing rules it out for highly sensitive code.
- It can lag behind upstream VS Code updates.
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.
