I've been using Arq for a few years. No majors issues, although I haven't had to test a full restore. I've been tempted to switch to Macrium as I already have a disk image using Macrium and switching would then mean I'm only using one piece of software instead of two.
But, with regards to file and folder backup, what would I miss by switching to Macrium? I'm a home user and not knowledgeable on the more technical side of backup software. I believe Arq does a full backup and incremental from then on. I know Macrium has this option also.
My main need is software that will never delete a file from a backup, no matter if I delete the source file or move it. Retaining a few versions. Bonus would be the ability to mirror this backup to the cloud in some form.
Currently, I have local backup to an external drive using Arq, and cloud backup to backblaze using their personal computer license. So it's two different pieces of software but that's not a problem.
