Stihl 461 vs Husqvarna 372 vs Dolmar 7910 vs Makita 7900 chainsaw

Testing out my four saws in a piece of fresh ponderosa pine. I was a little disappointed with the cuts for the Makita 7900. It has a mild port job done to it but I think either the wood pinched it or the chain/bar are boogered up. They both got pinched earlier in the day but I didn't notice any issues.
Any thoughts or suggestions are appreciated.
