In general, tren is known to have more sides. It's a much more anabolic and androgenic compound, so it tends to be harder on the system. Tren is generally never recommended for beginners, but I've seen plenty of people recommend deca and test as a beginner cycle (though typically, test alone is recommended first).
As manbeast said, everyone is different, you may do fine on tren, but very few people would be surprised to hear if you were unlucky enough to get lots of sides on tren.
