Zoho Remote Support- how is it compared to GoToAssist?

I currently use GoToAssist.  How does Zoho compare?

Does the client have to download any software? (My clients can barely check email, and they are doctors)

Is there a significant lag or buffer when in use?

What is the average upload/download speeds when transferring files?
