In my opinion, both the Magyars and Byzantines have very versatile tech trees in the game.
Personally, I prefer the Magyars because they excel at fast feudal builds due to their lower-cost scouts and free attack upgrades.
Additionally, their bonus against wolves makes them even more effective in the early game.
In the late game, the combination of Recurve Bow Cav Archers and Magyar Hussars make for a formidable army that can take on most other civilizations.
However, civilizations that specialize in Spearman and Scorpions, such as the Berbers, Britons, and Koreans, pose a significant challenge to this strategy.
To counter these counters, it may be necessary to mix in some Cavaliers or focus more on using Magyar Hussars, which also have a bonus against siege.
Overall, the Magyars are a strong civilization, but they do have some weaknesses that need to be accounted for.
