It's very easy to pull up contacts verified emails/cell numbers from LinkedIn and the pop up Chrome Extension is easy to use.

I like how this syncs so seamlessly from my Sales Nav to Outreach to SF.

I use LeadIQ on a daily basis, and would give it a slightly average score compared to other tools I've used in the space. Easy integrations with Outreach, Hubspot, and Sales Nav (though I've run into refresh and loading issues probably once a week with this one). Simple to use in order to collect contact data, and easy to set up.
