Best Tools for LinkedIn Automation and Multi-Channel Marketing

Hey folks, have gone through Expandi.io, HeyReach, Lemlist, LGM and Snov. The pricing is almost at the same level. What would you folks suggest if my primary requirements are 1. Flexibility with automation 2. Linkedin profile rotation 3. Easy setup between Email + LinkedIn + Call/Text channel Would be great if someone who used mutiple platforms can suggest :)
