HubSpot Sales Hub

Intuitive, easy to use, and it is effortless to customize. Hubspot sales and marketing modules complement effectively with each other. Workflows features allow to automate marketing efforts, allowing to scale operations smoothly.
It integrates smoothly with Gmail suite products, and mainstream business tools.

It does not count with advance lead scoring tools. Lead interaction tracking is limited. Workflow automation faces the same problem. As you start sophisticating your sales and marketing operations Hubspots tools may start falling short.

1) Grows with you
Although it offers a gazillion features and possibilities, just like Facebook, it just grows with you and how you use it. I tend to discover some additional possibilities along the way, even after +6 months of using it, but it always gets better for my use cases.

2) Easy sequences & follow-up
The sequences in Hubspot just work. Once set up - which is easy - I can add users one by one, tailor the message a bit and send out. Every mail sent is a mail I otherwise would have not gotten the time for to send it and just gives back results. It's more a sequence praise than Hubspot per se, but Hubspot's approach just works for me.

3) All-in-one
The fact that the landing pages can be created very easily, that you can send marketing emails, have chat on your website etc is a major plus.

4) Community
The fact they are big makes for a slew of Fiverr guys ready to help me out when in need.

1) Only community
Although I consider the fact they have a large community as a plus, the fact that you sometimes have to rely on the community to upvote features makes that my 'personal' impact on the roadmap is low. Even with a lot of upvotes there is no guarantee that Hubspot will alter the product.

2) Constant changes in pricing & feature lists
I have recommended others to use Hubspot for their features in a specific pack I use. However, pricing & features change so I sometimes mistakenly try to get people on board whilst pricing has gone up or features are missing for the acceptable pricing.

3) The neverending upsell
It makes sense that with more needs, more tools can be of assitance. But in Hubspot's case, there is a lot where we can still grow and where they can still charge me more. An acceptable all-in-one pricing would be welcome, because for now I do not use some features because of the big pricing gap.
