Slack

Pros

• The app ecosystem is very large, and tools such as ClickUp, Notion, HubSpot and Clockify can post updates into channels.
• Slack Connect lets teams work in shared channels with up to 250 outside organizations on paid plans.
• Compliance coverage is broad, including ISO 27001, SOC 2 Type II, FedRAMP Moderate and HIPAA configurability.
• Lists add table and board layouts with assignees, due dates and subtasks, without leaving chat.
• Workflow Builder automates routine requests and approvals without code.

Cons

• There are no native Gantt charts, dependencies, time tracking or portfolio reporting, so Slack doesn't replace a dedicated PM tool.
• Frequent notifications and busy channels can interrupt focus, a common complaint in reviews.
• The free plan keeps only 90 days of message history and allows 10 apps.
• Advanced AI features require Business+ or above, and per-user costs add up as teams grow.
• Reviewers report that finding older messages through search can be difficult.

SmartSuite

Pros

• The same records can be shown as grid, Kanban, Gantt, timeline, calendar, map and dashboard views without duplicating data.
• Its compliance coverage is unusually strong for the category, with ISO 27001, SOC 2 Type II, HIPAA and GDPR audits plus a choice of US or EU data residency.
• Read-only users, commenters and form submitters are free, which lowers the cost of involving stakeholders.
• It ships more than 200 templates and an AI solution builder to speed up setup.
• Reviewers describe the support team as responsive.

Cons

• Team, Professional and Enterprise carry 3-, 5- and 25-seat minimums, and there is no free plan.
• The Team plan allows only 5,000 records per solution, and automation runs plus API calls are hard-capped each month.
• SAML SSO and SCIM are available only on Enterprise and Signature plans.
• There is no team chat or whiteboard, and external access is limited to read-only shared views.
• Reviewers say complex workflows and large data imports take real setup effort, and there are no native desktop apps.
