Cvt vs hst

In the process of looking to buy a tractor. This is for 30 acres of mostly Woods with about 5 acres of pasture. I'm a hobbyist and my John Deere 410 (20hp) isn't cutting it. I was thinking of going with a new tym 474, but I found a Farmall 45c cvt with a cab and snow blower for a cheaper price than an open 474.

The Farmall 45 is a cvt. Is this good or bad? I shied away from a gear transmission due to hat's ease of use and loading ability. How does cvt compare?
