Here's why it's tricky to judge:
* Popularity Fluctuations: Names rise and fall in popularity. One might have been more popular in the past, but is now experiencing a resurgence.
* Subjective Perception: "Freshness" can be subjective. What one person finds fresh, another might find dated.
* Cultural Context: Popularity and perception of names can vary by region, ethnicity, and social group.
To get a better idea, you could:
* Check recent baby name lists: Look at lists from the last few years to see which name appears higher.
* Consider your specific context: Who are you naming? What is their background? What kind of vibe are you aiming for?
Ultimately, "freshness" is a personal judgment, and both Joshua and Jonathan are perfectly valid and well-known names.
