Quote: ... convince my why the Grendel is better than the .243
Its not better! Especially when comparing other bolt guns/cartridges.
The real advantage of the Grendel is that it fits in an AR platform. The Grendel is arguably more efficient, has less recoil and can fit in a smaller package.
Its horses for courses, whats the mission? IMO, in a lightweight bolt gun, the versatility of a fast twist 243 or 6 Creedmoor is hard to beat for varmints, predators, deer and pigs. If it aint broke .
