Glary Utilities is a comprehensive system utility suite. Here is how it compares:
Scope: Glary Utilities is a kitchen-sink suite with 20 or more tools including a registry cleaner, startup manager, file encryption, process explorer, disk analyzer, and more. RJL System Cleaner does one thing well -- it cleans junk files and privacy traces with a built-in duplicate finder. If you want a single-purpose tool that is simple and focused, RJL System Cleaner is the better choice.
Complexity: Glary's 20-tool interface can be overwhelming. RJL System Cleaner has a simple mode designed for non-technical users and an advanced mode for power users.
Registry cleaner: Glary includes a registry cleaner, which can cause system instability. RJL System Cleaner intentionally excludes it.
Bundled offers: Glary Utilities may include optional software offers during installation. RJL System Cleaner has no installer and no offers.
Price: Glary Utilities Pro costs approximately $20 per year. RJL System Cleaner is free, or $19.99 once (not a subscription) to register.
Portability: Glary Utilities requires installation. RJL System Cleaner is a single portable .exe under 5 MB.
Where Glary wins: If you want an all-in-one suite with many different system tools in a single package, Glary offers more breadth. But for focused, trustworthy junk file cleaning, RJL System Cleaner is purpose-built for that task.
