Whether to use Google Tag Manager (GTM) triggers for Google Analytics 4 (GA4) or integrate GA4 directly into your web project depends on several factors, including the complexity of your tracking requirements, your team's familiarity with GTM, and your project's specific needs. Here's a breakdown to help you decide:

Integrating GA4 directly into your web project:

1. Direct Control: Integrating GA4 directly into your web project gives you direct control over the implementation. You can customize the tracking code exactly as per your requirements without relying on GTM.

2. Performance: Direct integration may offer slightly better performance since there's no additional layer (GTM) between your website and GA4.

3. Flexibility: You have more flexibility to handle complex tracking scenarios, custom events, and data layer implementations directly within your codebase.

Using GTM triggers for GA4:

1. Ease of Management: GTM provides a user-friendly interface for managing various tags, triggers, and variables. It's particularly useful if you have multiple tags to manage or if you frequently update your tracking configurations.

2. Reduced Dependency on Developers: With GTM, marketers or analysts can manage tags without needing developer involvement for every change. This can speed up the process of implementing and iterating on tracking configurations.

3. Version Control: GTM offers version control features, allowing you to roll back changes if needed, which can be handy for maintaining tracking configurations over time.

Best Practices:

1. Combination Approach: In some cases, a combination of both direct integration and GTM may be appropriate. For example, you might integrate basic pageview tracking directly into your project while using GTM for more complex event tracking.

2. Consider Future Scalability: Evaluate your project's scalability needs. If you anticipate significant changes or expansions to your tracking requirements in the future, GTM might provide more flexibility and easier management.

3. Team Collaboration: Consider your team's skills and collaboration workflow. If you have a dedicated analytics team or if developers and marketers work closely together, GTM might streamline the process.

4. Performance Considerations: Assess the impact on page load times and overall performance. While GTM is generally efficient, adding unnecessary tags or triggers can impact performance.

5. Documentation and Governance: Regardless of your approach, maintain thorough documentation of your tracking implementations and establish governance practices to ensure consistency and accuracy in tracking data.

Ultimately, there's no one-size-fits-all answer. Evaluate your project's specific needs, team capabilities, and long-term goals to determine the best approach for integrating GA4 tracking into your web project.
