Every remote support tool can connect to a laptop and share a screen. The differences that actually matter only show up once your helpdesk is using the tool every day, not during the sales demo.
Check how sessions are logged and who can review them later. In regulated industries this is often the deciding factor, not the interface or the price.
Also worth checking: how the tool behaves on a slow connection, whether unattended access is handled securely and how quickly a technician can actually get into a session during a real incident.
Tools like TeamViewer are built for this kind of daily use at scale, which is a different bar than simply working well in a fifteen minute demo.
