1. Language Compatibility: Helios is written in Java, while Helm is written in Go. This difference in programming languages impacts the community and developers who are more proficient in a particular language.
2. Scope of Usage: Helios focuses on providing cluster orchestration and management, whereas Helm is predominantly a package manager for Kubernetes applications. This distinction affects the use cases and functionalities offered by both tools.
3. Resource Management: Helm leverages the use of charts and packages to manage resources, simplifying deployment processes, whereas Helios relies on a different approach for managing resources within a cluster, which may have different implications in terms of resource utilization and optimization.
4. Community Support: Helm has gained significant traction in the Kubernetes community with a large and active user base, contributing to its continuous development and improvement. In contrast, Helios may have a smaller community base, affecting the availability of support resources and updates.
5. Customization Features: Helm provides a robust templating system that allows for extensive configurations and customizations, offering more flexibility in application deployments compared to Helios, which may have limited customization options.
6. Maturity and Stability: Helm has been around for a longer period and has reached a more mature and stable state compared to Helios, which might still be evolving and undergoing changes. This discrepancy in maturity level can influence the reliability and performance of the tools for production environments.

In Summary, Helios and Helm differ in language compatibility, scope of usage, resource management, community support, customization features, and maturity/stability levels.
