Best comprehensive CRM system for managing customer interactions

Hi all,

I’m currently exploring CRM platforms that offer a comprehensive approach to managing customer interactions across the entire journey—sales, onboarding, support, and ongoing engagement. Our team is growing, and we’re looking for a system that can centralize these touchpoints and help us stay proactive with accounts.

During my research on G2, a few platforms stood out:

• Zoho CRM – Looks like a strong all-in-one option with customization flexibility.
• Salesforce Sales Cloud – Enterprise-grade, but I’m curious how complex the implementation is.
• HubSpot CRM – Seems intuitive and great for marketing and support integration.
• Microsoft Dynamics 365 – Robust, but wondering how it stacks up in terms of user experience.
• Insightly – Interesting mid-market contender, especially with project tracking built in.

Has anyone here implemented one of these across multiple departments? Would love to hear how well they handle real-time visibility into customer health, support history, and follow-ups—especially in fast-paced environments.

Appreciate any firsthand experiences or watch-outs!
