Which is better for Lead Generation: Hubspot, Adobe Marketo, or Salesforce Pardot?

Hey guys! First off, thank you in advance for your insight.

My company is mid-sized and we have several profit centers, meaning we have quite a global outreach, and we're still expanding. I've been tasked to research into lead generation tools and I'll be honest… after hours of researching, I'm still not sure what exactly I should be looking at which is why I'm here asking for advice.

To give you a clearer picture, I'm trying to figure out which software (Hubspot, Marketo, Pardot) would be more efficient in lead generation automation – meaning, handling large amounts of data with respect to data hygiene. Also, a big one would be ease of use and upkeep. Budget isn't a problem as far as I know.

If you have any other suggestions on other products I should be looking into or if you require any further information to better assess my needs, do not hesitate to ask 🙂

Again, thank you so much for your help guys. Greatly appreciate it.
