Which is more life-threatening bradycardia or tachycardia?

It would depend on how tachy or how brady the patient is. Both can be equally life threatening.
"Neither" and "Both" are equally correct.
Both of those terms simply refer to a HR within a common range or outside of a common range. Depending on the factors affecting a patient's perfusion and cardiac output demands, a HR of 55 might be more than enough for one person, but life threatening for another. Likewise, a HR of 130 might be totally appropriate in someone under high physiological stress, but unsustainable for someone else.

Also depends on what's causing it.

I always say too fast is better than not enough but that comes with a big asterisk.

Assuming this is a homework question like it appears to be, how about you tell us your thoughts first?

I dunno. I've seen some perfuse ok with a hr of 29-40, hypertensive, but some not tolerate 160 at all. No time for the ventricles to fill.tend to get hypotensive
What are your thoughts on the matter?
What is the context of the question?
Thats why it comes with a big asterisk. It doesn't apply to all situations.
As a practical matter, I'd rather treat too slow than too fast. Less to think about, differential list is shorter, overall easier to treat IMO

I am curious to find this out as well. Short answer: both can be not so bad, both can be really bad. It depends on how high or low and on the overall clinical picture.

Both can cause unstable hemodynamics and it's the unstable hemodynamics that kill, not the blood pressure itself. It's all about the oxygenation, and if that's not happening then it's over. A tachycardia can turn to V Fib which is lethal, and sinus brady can turn to worse sinus brady and then asystole which is not compatible with life.
