You don't have to play a lot to know this.
Yes, you don't have to coil as much for 2 HBH and you can hit ball later in the stroke - that's closer to your body. 1 HBH you must rotate shoulders a wee bit more as you normally use neutral or closed stance, and contact point is a foot or more out front. Getting that extra coil and extra foot of early contact takes a bit more time. You can get away with more such as open stances and later contact and still hit an agressive shot with 2 HBH.
But, a good 1 HBH is prettier.
