RemotePC vs Supremo Remote Desktop : Which is best for you?

You will get what you pay for. If you need a simple inexpensive software to jump on a computer from time to time, then it will work. If you want longevity and be able to act like you are right at your desk, then there is way better options that are not much more money.

On some remote computers with dual monitors, I've had occasional display issues. While I can still view both screens individually, the presentation isn't always seamless on dual screens.

I've been using Supremo for a few years now, and I really like the simple and clean interface.

It can't handle multiple monitors at the host end, so sometimes you have to ask the host user to move windows from one monitor to another.
