If I were building a system for gaming, office work, or everyday use, I would feel confident using it. However, I would not expect it to compete with high-end dual-tower coolers for heavy overclocking.
Noise Levels
One thing I always care about is noise. In my experience, a good cooler should keep temperatures under control without sounding distracting. The Assassin Spirit 120 Evo seems like a reasonable choice if I want a balance between airflow and quiet operation. I would still check fan curves and BIOS settings to fine-tune noise levels for my own setup.
Build Quality and Design

The tower-style design is simple and efficient, which I find useful in a no-nonsense PC build.
