How the experiences actually differ
Space Mountain delivers a full-scale thrill coaster, with an intensity profile of “High: speed, drops or forceful coaster motion (database thrill rating: 4/5).” Big Thunder Mountain Railroad instead delivers a full-scale thrill coaster, with “High: speed, drops or forceful coaster motion (database thrill rating: 4/5).” That difference is more important than a single average-wait number: a short wait is not a bargain if the ride's motion, soak level or format does not suit the people in your party.
How to fit each into your day
Neither is an automatic first priority solely from ride type; use the live waits and your group's preferences to break the tie. For Space Mountain: Treat it as an early-day or monitored-wait priority; headliner coaster queues are least forgiving at midday. For Big Thunder Mountain Railroad: Treat it as an early-day or monitored-wait priority; headliner coaster queues are least forgiving at midday. Do not lock both into fixed times unless they are true must-dos; monitoring both waits gives you room to take whichever reaches a favorable window first.
Can you realistically do both?
Yes. Both are in Magic Kingdom, so doing both is realistic without changing parks. The efficient approach is to protect the less flexible queue first and treat the other as a live-wait decision. If your group splits on intensity, use Rider Switch or a nearby lower-intensity experience where available rather than forcing everyone into the same choice.
Final recommendationSpace Mountain is the better use of time when your party wants a full-scale thrill coaster. Big Thunder Mountain Railroad wins when the group instead wants a full-scale thrill coaster. Track both and take the first genuinely useful wait window.
