The fact you can have multiple versions for different countries or languages makes this software really useful! It's very easy use but not as powerful like other similar softwares out there (like HubSpot).
I would say try them both before making your decision because they do offer many features each with its own unique benefits - however Market Relaye does work better if used together within our organization so we're actually using two solutions here at my current job which was difficult when implementing into an existing system without taking time during training phases etc.. If price isn't important then go ahead just stick around until Salesforce releases something equivalent since it will be hard replacing once released by another vendor unless sales force pulls off some amazing stuff haha ;) Give us access from anywhere via mobile devices too :) We are solving several problems including managing internationalization requirements while also ensuring compliance through GDPR/Cookie law rulesets along side general data protection regulations such has PCI DSS & ISO 27001 standards.
