In the former case petrified wood can be (more) beautiful uncut. In the latter case, breaking open a piece of petrified wood using a hammer may yield a fresh rock surface, which could show different details. However it is probably more rewarding to cut the petrified wood, e.g. with a slow saw.
As Auspex says, reversibility is important, thought perhaps not so much with a common pet wood piece, but if you value it any, you don't want to do something that you might regret later. I have a few Hornby Island fossils that I received from some old rockhound that are slathered in what looks like some kind of epoxy!

It's mixed in with lots of chert nodules of the same color, so it's not always easy to tell the difference between the two.
As I recall the Blue Forest wood had interesting preservation that entailed a layer of algae that encased the pieces as well as silica-laded Eocene age volcanic ask that entombed and petrified the wood. Most pieces show a light tan 'rind' around them which I take to be characteristic of the Blue Forest wood.
I was creek walking today and found this 15 lb piece of petrified wood. I looked up similar sized pieces but I feel like this may be "extra cool"? I don't know much about fossils but I have a passion for wood formations and this seems to be a knot from the tree with the burl or tumor in tact on t...
Glad to have a forum to ask questions like the following.

Tapped it with my rock hammer and it split in half exposing the inside. Found a lot of other interesting petrified wood ...
