[Star Wars] Is there any tactical advantage to a walker that cannot be fulfilled by a regular tank?

So, walkers look cool and all, but why use them? They seem like an engineering nightmare, they have the most obvious weak point ever, and what specific advantage do they offer that cannot be achieved by just using a big tank?

I wondered about this before, and a kind person explained it to me. It's mines. 

You can't roll over a mine and expect your tank tracks to survive it. Sure, you and the tank's hull might actually be fine, but you're stuck in place until the engineers can get over and repair them, which they aren't going to do until the battle has ended or at least moved away from you.

On the other hand if you have big dumb feet which are basically a solid two metre block of \[Star Wars armour\], you can stomp right down on one and keep on strolling. 

Thus, when you are attacking an entrenched enemy position like Hoth and don't have time to wait for mine-clearing, you send in walkers.
