Overall, my experience with Salesforce Sales Cloud has been largely positive. A very powerful CRM platform that can handle complex sales processes with lots of customization as business needs change. I think flexibility is one of the biggest strengths. Ecosystem around salesforce is excellent. The support is good and really helpful. Customization comes with a steep learning curve but once everything is set, It is the best CRM for almost all sales processes.

Salesforce Sales Cloud is a great tool and very customizable platform, but their post-sales service and experience leaves much to be desired even if you are in a large billed customer. They will constantly market to you, without actually looking at what you're doing or how you're using the product. Paying for premium support does only guarantee you a fast response, but not necessarily a quality one.
