Since Aliasgar placed a recent post, I’ll put in my two bits again.

I use Macs, home and office, each running a Win8 virtual machine. I mostly connect between the Macs and from iOS devices to the Macs.

I’ve been using Back To My Mac, Google Chrome Remote Desktop, LogMeIn, and GoToMyPC on the Macs and LogMeIn Ignition and GoToMyPC on the iOS devices.

Frustratingly, none of these is completely reliable in making connections. GoToMyPC is the most reliable, but it costs money, and occasionally won’t connect. Very frequently, if one of the services won’t connect, one of the others will, so it is useful having all available if remote access is important as it is to me.

On the Mac desktop Back To My Mac has the best interface with Chrome Remote Desktop second.

On the iOS devices LogMeIn certainly has a better interface than does GoToMyPC. I bought Ignition some years back, and it may give me ongoing use of LogMeIn even though the free desktop version is no longer available.
