It’s impossible to provide any useful answer to this question without further context of your specific needs, as the best solution for you depends on your business objectives and goals. Your current and planned technology mix is also a big input. We’ve seen Oracle Sales Cloud gain significant traction in the market and it’s a solution worth investigation, especially if you have a Siebel infrastructure. As an Oracle Diamond Partner, we help our clients evaluate, choose, and implement technology solutions. Please reach out if you’d like to talk further.
