Introduction: Two Generations of Office Compared
Microsoft has launched Office 2024 as the natural successor to Office 2021, bringing significant improvements in performance, security, and — for the first time — features based on artificial intelligence. However, Office 2021 remains a popular choice for those seeking stability and a competitive price.
In this guide, we compare the two versions in every aspect to help you understand which one is really worth it in 2026, considering your working style, budget, and specific needs.
The New Features of Office 2024
Office 2024 Professional Plus represents a generational leap compared to its predecessor. Here are the most relevant new features:
- Microsoft Copilot Integration The AI assistant integrated into Word, Excel, and PowerPoint generates drafts, summaries, formulas, and presentations from simple text prompts. It's like having a personal assistant always available.
- Improved Performance App startup is up to 30% faster, improved handling of complex Excel files with millions of rows, and smoother PowerPoint rendering even with heavy animations.
- New Excel Functions 14 new functions including GROUPBY, PIVOTBY, and IMAGE that allow for more powerful data analysis without resorting to macros or VBA.
- Renewed Design Updated interface with the Fluent Design System, improved dark theme, and new accessibility options for better readability.
- Advanced Security Enhanced protection against phishing in Outlook, improved document encryption, and integrated Data Loss Prevention.
Office 2021: Strengths
Despite the arrival of its successor, Office 2021 Professional Plus maintains several concrete advantages:
- More Accessible Price With a significantly lower cost compared to Office 2024, it represents an excellent option for those on a limited budget.
- Proven Stability After years of use and updates, it is a mature, stable product free of significant bugs.
- Total Compatibility Supports all .docx, .xlsx, .pptx formats and integrates perfectly with OneDrive and Teams.
- No Subscription Like Office 2024, it offers a perpetual license: pay once and use forever.
- Lower Hardware Requirements Works perfectly on older PCs where Office 2024 might be heavier.
