Which is more subject to the effects of recoil?

No real clear cut and dried answer here , because some scopes are intentionally built heavy to withstand recoil shock better. Some others are just plain heavy,  but no tougher than some good lightweight scopes.
A heavy scope  always puts more stress on the mounting system than a light one does, all else being the same.  Simple physics.

Consider the weight of the scope AND the weight of the rifle. 

1/2 mass x (velocity x velocity):  Lord Kelvin was right.

Exactly. This is the reason that with what might called "conventional" scopes, the smaller, lighter scopes tend to be more recoil-resistant, especially fixed-power scopes.

The really heavy-duty "tactical" type scopes such as Nightforce and others are also very recoil resistant, but keeping them connected to the rifle precisely also requires heavier-duty mounts, as RONK pointed out.

Ok, so how does a standard Zeiss match up to a Leupold in this regard?

Twenty years ago I would have definitely given the edge to Leupold, but today's Zeisses are a lot tougher than they used to be. What sort of rifle are you planning to put it on?

I've seen a Conquest die, I have sen MANY Leupolds die, all is frame of reference.  The Conquest was on a Barrett .50cal - where it should not be.

What is the rifle?
What is the caliber?
What is the "need" and the want - and thee are usually quite different.

Sir Isaac Newton I believe once said "a body at rest tends to stay at rest." Point being as the rifle recoils the scope wants to stay where it is. The heavier the scope is the more it wants to argue and not move. The scope mounts and ring friction have to resist this and force the scope to comply. A light weight scope puts up less of a fight. The same applies for each internal part of the scope. A heavy lense will want to stay put as the scope moves. In this case rifle weight is your friend as it also wants to stay put as the bullet moves forward. The heavier the rifle is the less force that is applied to the scope, mounts, lense, 'et all. Scope longevity is determined not only by manufacturer but by bullet weight, rifle weight, and velocity of said bullet. The worst combination is an ultra light rifle of large caliber with a heavy scope. Doesn't do your shoulder much good either :)

Model 70 Winchester, about 30 years old......not entirely sure how well the rifle shoots as I've not had much range time with it.  If it shoots tight groups I'd like to put good scope on it that will last a lifetime.

pass-thru,
 
We need to know the chambering of the rifle, not just the brand.

It's a .30-06.

Either a Leupold or Zeiss should hold up pretty much forever on a .30-06.

Regardless of a cartridge`s recoil, I prefer a lighter scope. There are many ways to offset heavier felt recoil on the bench without adding more overall weight to a hunting rifle by adding a heavier scope.

Except for the Super Sniper I have never held a scope that was heavy enough to matter, un less it was going on a really light 5.5# or 6.5# rifle, for hunting sheep?

I have some heavy scopes, best to buy really good mounts, else they do tend to move on recoil.
