Deployment and data
Both are cloud tools with no server to run, so deployment is not the deciding factor. Export format and data portability are worth more attention, because a simple CRM is often a stepping stone rather than a permanent home.
The size of team each is shaped around
Both are built below the enterprise line and aimed at teams counted in single or low double digits. The useful question is what happens at the edges: multiple pipelines, territory splits, permission tiers and a second office. Ask each vendor how those are handled today rather than assuming.
Breadth versus depth
Simplicity is a feature until it is a ceiling. Both products deliberately leave out capability that a broader platform includes, which is exactly why they are pleasant to adopt. Decide honestly whether you will need campaigns, calling and messaging within a year, because adding three tools around a simple core costs more attention than one slightly larger tool.
Implementation effort
Low in both cases, measured in days rather than weeks for a small team. The real work is deciding conventions and cleaning the contact list you are importing. Importing a messy spreadsheet into a clean CRM produces a messy CRM.
Channel coverage
This is where lightweight CRMs differ most from conversation-heavy sales. If your enquiries arrive and progress on WhatsApp or by phone, check carefully how each product records those exchanges, because email-shaped tools can leave your busiest channel undocumented.
