On aberation you need big quantitys of fiber for ziplines so I suggest you use a dire bear for getting shrooms for recipes and spore immunity, and fiber of course. IMPORTANT to maximize your fun and travel use the zip lines while your riding a ravager/giagantopithicus
On mobile, I take a dire bear, double tap and hold to do repeated attacks, and just run through the jungle. Just make sure to dump the berries as they fill up your weight easily, and beware of raptors.
Moschops can gather fiber, but if they are far away from your tames (even if its on neutral), anything attacking it, even compys will kill it. Moschops NEVER fight back, they just run. I have one and some foolish dilos attacked my dinos, so we easily slaughtered them. Unlike the others, the moschops just ran away. Neutral aggression? More like coward aggression.
