Pros & Cons
Attio

Pros
- The custom objects and attributes let teams model non-standard processes such as fundraising or partnerships.
- Email and calendar sync builds and enriches contact and company records automatically.
- A Free plan for up to 3 seats and transparent per-seat pricing make it easy to start.
- Pro call intelligence records Zoom, Meet and Teams calls and fills fields from transcripts.
- Developers get API access on every plan, plus webhooks, an App SDK and an MCP server.
Cons
- The native integration catalog is smaller than HubSpot's or Salesforce's.
- Mailbox sending caps make it unsuitable for high-volume outbound SDR teams.
- Plus stops at 10 seats, so the 11th seat forces an upgrade to Pro.
- AI features and workflows draw on credit pools that can run out.
- Reviews say the mobile app has fewer features than the web version, and some report inconsistent support.
Microsoft Dynamics 365 Sales

Pros
- Works natively with Microsoft 365 and the Dynamics 365 and Power Platform stack, which suits firms that already run on Microsoft.
- Deep customization and automation, which reviewers often name as a key strength.
- Copilot features and prebuilt AI agents are included from the Enterprise tier, and Premium bundles 1,000 Copilot Credits per user each month.
- Flexible licensing, including attach licenses for existing Dynamics 365 users and device licenses for shared machines.
Cons
- Steep learning curve, the most common complaint in G2 reviews (3.8/5 average from about 1,600 reviews).
- Setup and customization are complex for non-technical users and usually need an admin or partner.
- Advanced features and AI capacity cost extra, and Premium more than doubles the per-user price of Professional.
- The Professional tier has limited customization, which pushes many buyers to the $105 Enterprise tier.
