Paid options are always better than free or at least we tend to think so.

Most free programs are trial versions or come with limited features or worse still, show plenty of ads or slow down the PC. To avoid these and to appreciate the hard work behind creating these tools you should opt for paid versions if you have the resources.

Having said that, I have used all of these free programs on my last PC before upgrading the hardware. I have not found any of these programs interfere with one another or restrict the other to do its task.
