Have been using HubSpot for CRM, supplemented with Pylon for CX. The combo has worked well for us because HubSpot handles the broader CRM workflows, while Pylon fills some of the gaps on the customer success side.

Pylon has been rolling out some interesting capabilities lately - Account Intelligence in particular has been useful for surfacing context automatically before a human jumps in. Still early, but it’s been helpful in reducing back-and-forth.
