Hi, Overall bike is completely different than EXC. There would be so many things to talk about but key difference for me is. 1. Power, it actually feels like 300 2 stroke carbs in the past. Mid to top is much stronger in a good way and controllable. From very low RPM's like idling area, its weaker. If you have any kind of momentum it's good. 2.Gearing, i like 5 speed trans more. Seems to fit much better than KTM 6 speed. EXC had always issue 3-4 gear. It's too short or too wide. XE300 it's a good bike for sure :)
