Sorry it took me awhile to reply, FF. The last couple of days have been hectic, and I've only been able to hit & run here.
Binos or reflectors, hmmm. I suppose that would be a matter of personal choice. I personally think binoculars are bulky and have no advantages other than twin eyepieces. That would be especially true of binoculars powerful enough to view a 0.3 inch hole at several hundred yards. At that power, it would also be impossible to hand hold them and keep them steady.
A reflector binocular? I'm getting this mental picture of binoculars almost two feet wide

Refractors were very popular in past years, since they were the standard for centuries before reflectors came along. When they finally did come onto the scene, the good ones were expensive and the ones available to the average Joe weren't all that great.
The Schmidt-Cassegrain system has been around for a relatively long time and is more complex and demanding than the Maksutov-Cassegrain system, but it's still pretty much the standard for better scopes. I'm not familiar with the technical differences between the two, but I do know that Maksutov-Cassegrain is relatively new, and while the Schmidt is better, it's also much more expensive to manufacture. The Maksutov-Cassegrain system is a simpler system with fewer parts, and that, coupled with computer controlled mirror grinding machines, put decent and powerful optics well within reach of the casual amateur. Except for specialty items like rifle scopes, I think that refractors will become all but extinct someday.
Between the two you mentioned, I would definitely go for the telescope, if for no other reason than its ability to let you see in low light. Binoculars just can't touch it in that aspect.
The only catch I can think of is that reflectors are generally more fragile than binoculars or refractors. You can mount lenses in pretty sturdy mounts (as in rifle scopes), but the mirrors and their mounts require more precision and the wider tube makes it more susceptible to jarring and impact. Still, a half decent scope will hold up to average abuse. Just don't try to mount one on a .300 Win Mag
