Acronis is the most popular of the two, and for good reasons. They have so many options in the package.
In an earlier post, I stated that it was a little slow, but effective. How quick it finishes depends on a couple of things. First, how many partitions you have (I have three, loaded with software, not just a "C" partition) has everything to do with time. On my first backup, it took almost 70 minutes to complete, to my Seagate FreeAgent Xtreme backup drive. I'm not 100% positive, but I think it runs at 5400rpm, which would be slower than one running at 7200rpm. I'll have to double check on that spec (the drive speed).
Also, the type of connection you have to the drive makes a world of difference. If you have an eSATA port, and your backup drive does, that 70 minutes would be cut at least in half, if not more. Mine is connected through USB 2.0, which is naturally going to be slow, especially backing up 3 partitions.
After your first backup, then all you have to do (if you want to) is update the backup that you've already done, and it doesn't take near as long. I update the backup after Update Tuesday of each month, and after making any major software changes. For example, I'm installing XP Mode on Ultimate as I'm typing this post, and I'll update in the morning. I prefer to do incremental for two reasons, it's quicker, and preserves space on your backup drive.
As soon as my WD Caviar Black (750GB) returns, they emailed me today, approving my claim, I'll reinstall it in the drive case it came out of, and I'll make another 500GB partition for backup out of that. The remaining will be used to run Linux from. They stated that the turnaround is 5 to 7 business days.
And as I always do, I have one image taken with the free version of Macrium on hand. It doesn't hurt to have an extra image on hand, if you have the space.
Overall, I feel that you'll be very satisfied with Acronis, I never meant to imply that the software was slow, but if you have a lot to backup, using a USB 2.0 connection, don't expect to be through in 10 minutes. And as I've already said, you don't have to baby sit it, you can check the box to shut down when finished.
And the recovery manager is an excellent extra to have on hand. It always displays prior to your OS boot choices. I used to love OEM recovery partitions, but not no more.
Give it a test drive, I think that you'll be satisfied.
