Top Data Vendor Recommendations for B2B2C Marketing Companies

Hey folks - wondering what people's preferred data vendors are? We're currently looking to switch from Apollo as we don't want the same vendor for sequencing and data. We are a b2b2c marketing company focused on large enterprise consumer brands in the North American market. The solution needs to have robust account and contact level data, and integrate well with Salesforce and ideally also Outreach who are likely going to be our vendor for sequencing going forward. Not too fussed about intent data and various claims of AI market intelligence, I just want good data in an easy to consume format with reliable support. I know Zoominfo are big in this space but they're quite expensive for what you get. Seamless? Hubspot Breeze? I know the cool kids are on Clay but the learning curve and bottle neck-y nature of the tool is a deterrent. What are the second coolest kids using these days?
