Is Upgrading to the Growth Plan Worth It for Salesforce Integration with Nooks?

Hi all, I'm currently on the legacy explorer plan which works fine connecting with lemlist etc, however we are moving our outbound over to Nooks (operates through salesforce data), and the explorer plan does not have the SF integration as part of the plan. At the moment i'm having to prospect in clay, cross reference with our full salesforce lead list which i have exported to clay, match the salesforce lead id, and then use data loader to upload/update the leads in salesforce Would make my life much easier if i were to upgrade to the Growth plan, just wanted to hear people's feedback on the salesforce integration, does it work well and would it be worth the investment?
