Prefers the Aligned Continuity.
Predacons are prehistoric now-extinct Cybertronians who, as their present-day clones attest, are very powerful physically and possibly indestructible by conventional means accessible to most Autobots or Decepticons.
Dinobots are the result of Shockwave's lab experiments on some Autobot captives during the War for Cybertron. They are also very powerful physically and difficult to take down.
When discussing the reappearance of Predacons in Transformers: Prime, Ironhide comments that Predacons are a "totally different thing" from Dinobots, in a tone that implies they are a greater threat than that. However, it should be noted that Predacons have been extinct and do not exist in living Cybertronian memory, so myths about the Predacons' power may have been exagerrated. Where the Predacons did make an appearance, they did display incredible physical prowess against regular-sized Autobots and Decepticons alike, yet we have not seen them up against the more powerful Dinobots.
Both Predacons and Dinobots prefer to fight in their strong, brutish beast forms. Do we have any indication on how exactly the two would fare if they are to clash head-on?
Edit: Just in case, I'd like to clarify that I'm not simply asking "Are Predacons more powerful than Dinobots?" Left as it is, such a question would be open to speculation. Specifically, I'm asking if we've any official information that would give an indication, direct or indirect. In other words, I'm not looking for speculation not based on official sources.
