Back to Basics is no Blood Moon for sure but its still better than Armageddon.
Decks you board your anti-land plan in usually play more lands, can usually recur lands and play Wastelands/Manlands. BtB costs one less and with basics fetched out you can still operate quite normal because your deck needs only 3-4 mana. Landstill on the other hand is severely crippled for at least some turns and will have to play slower than usual. BtB also shuts down his Mishra win condition. With crucible he can begin to waste his lands to recur them untapped but needless to say that it is slooow.
Geddon destroys your precious (basic)lands and your opponent will be more likely recover earlier than you. Crucible also makes Geddon a dead card while BtB is still good. And to use Geddon to full effect you need a beater out. BtB does not depend on other cards.
