I need to cut some smallish holes in 4" (about 3/4" diameter) sandstone
brick and have heard suggestions of using either a core drill or a
roto-hammer. Interested in hearing any thoughts on this before committing
myself. What are the chances of cracking the stone with either one but
especially the hammer?

I have no idea what "smallish" means. Hammer drills work great! Buy a
decent drill bit, by the way. You might be able to do this with an ordinary
electric drill and a decent masonry bit. Sandstone is easy to drill with a
good drill bit.

Being sandstone I would go with a standard drill and quality masonry bit.

I just did that into a 12" thick piece of rock/sandstone. I wanted to run
vinyl tubing thru it for a fountain. I rented the mid size BOSCH hammer
drill from Home Depot that takes the SDS MAX (about 1" shank: 4 carbide
tips) drill bits you get when renting the drill. I used a 3/4" X 14" bit
and it breezed thru in about 3 minutes..I removed the bit from the hole
every inch or two so and blow it out with compressor air.. After that, I
drilled 2 holes in my 9" thick foundation..that was a breeze.

As far as cracking, I guess it depends on how big your "brick" is
