Pros
Pro FinderMinder support
FinderMinder allows you to specify where (position) and what size you want newly opened Finder windows to appear. The default Finder behavior is to remember the last position and size for every window, but this can be frustrating if you already know where you want every window to appear (for example, centered at 800x600). FinderMinder must be running for window reposition and resize to take place.
FinderMinder must continue running in the background for window reposition and resize to take place, so click the "Hide" button to dismiss the preferences and keep FinderMinder running. Simply re-launch FinderMinder to access the preferences again or to quit the app.
Pro Cheap and has a free trial
The app costs just $3 and offers a free trial for testing it out before buying.
Pro Has almost all the features needed in a window manager app
I've tried almost every app on this list. I thought it was amazing how many there were out there by the time I finally stopped experimenting and searching for the one I liked most. I chose Optimal Layout mostly because it was sufficiently extendable and felt lighter to use than the others. There were lighter ones, but those were very limited in their features and customizability.
Pro It's free! Which is fair as it manages only windows for Finder.
The price is right! It comes from a great source of developers who already have window manager apps on this page's list. I am not sure what they plan to do with this app in the future, whether to keep it light and by itself and work in conjunction with their other window managers, or add this feature solely to one of their other fully featured window manager apps.
Pro Beginner-friendly defaults
The default configuration includes everything except for system files to be backed up. That also includes external USB drives. This will work for most people. It can, of course, be customized to each person's liking.
Pro No file size or traffic restrictions
There are no limitations of file size or amount of data you can upload. The $5/mo plan gets you unlimited cloud storage.
Pro Excellent restoration performance
Backblaze creates a zip file of all your files for you to download, thus decreasing the amount of data you need to download and increasing the speed of the download since it's one connection instead of multiple that need to be opened and closed for a list of files.
Pro Secure
AES encrypted files are transferred over a secure SSL connection.
Pro Download any backed-up files from any web browser
Some backup services like Carbonite require a client to be installed to restore files. Backblaze allows you to login and download any or all files from a web browser, meaning it also serves as an ad-hoc cloud storage platform.
Pro Users can order a physical copy of their data
You can have a flash drive or an external hard drive delivered to you. They cost $99 and $189 respectively.
