Crucible is just plain better than Sacred Ground.
This is true in most cases. A Crucible of your own has many more uses than Sacred Ground has, since it is a disruption element on its own. Sacred Ground is a purely defensive measure, which does - by default - not help you win. So, in a Crucible Control matchup, Crucible is better than Sacred Ground by a huge margin. The necessary counter-measure is artifact destruction vs. their Crucible, which lets you gain a serious advantage once you have your own CoW. But if CoW stands against CoW, the effect is entirely symmetrical. The board position (regarding lands) stalls until one finds artifact removal.
There is one case, though, where I can see Sacred Ground actually being better than Crucible, and that is versus Titan/Crucible-decks. Here, a single Titan can destroy almost your complete mana base, and backed up with Wasteland/Crucible, being able to play one land each turn from your graveyard will not let you get back into the game. Not at all.
Sacred Ground will negate that game plan entirely and reduce the Titan to a vanilla 7/10 creature. If I see this correctly, your opponent must choose a land of each type (even if he chooses one Dual twice), and you wil be able to actually gain mana from his Titan by tapping your lands for mana before they go to the graveyard. They will return untapped from the Sacred Ground trigger.
Of course, if your opponent has a Crucible out, your Wastelands are moot, as Johnstown correctly pointed out. So you will have to decide if A) you are willing to reduce your Strips to early-game tempo tools and B) you are expecting Crucible/Titan-decks to dominate your metagame. A) is fair, but B) is as yet unlikely to happen, and it is the only time I'd personally prefer Sacred Ground over Crucible.
As for Smokestack, Crucible is fine there, too, and there are other ways to combat it (e.g. Soldiers from a Decree, artifact removal). With Crucible/Wasteland on
your side, your opponent is likely to be short of permanents himself, so Smokestack deals with itself.
I have not tested Sacred Ground in these matchups. Perhaps I should test before I post.
Definitely you should, as should everybody else. Your post, however, was not a bad attempt at a first one, because it raised a valid question of general interest. That is my opinion, but you will soon notice if a Mod thinks otherwise.
