Most kinds of averaging meters (under most conditions) will work far
better than a spotmeter used unintelligently.

For ascertaining the contrast range in the scene quickly, though speed
and spot do not necessarily go together.

One's estimation of a "midtone" is the operant parameter here.
Misestimate the reflectance of the area you're relying on by 1/2 stop (far
easier to do than most would believe) and there goes the exposure (at
least from where you wanted it). I always hear people say they use "grass"
(no, not THAT way, geez) as the "midtone", but has anyone measured
reflectance in grasses, across the seasons and varieties thereof ?
An El Ni~o-year grass patch looks a lot greener and darker than
one during La Ni~a.
Enlightenment ? That's a product from India, I believe...
