Mobile Demon Altar or Crimson Altar?

I have a world with only crimson altar and my friend has demon altar, What do you think is better? Since I can't get some clorophyte ore like him.

I'm not sure what your question is. When a world is made, it is randomly created with either the Corruption biome or the Crimson biome. If you have a Corruption biome, your world will have Demon Altars. Crimson worlds have Crimson Altars. Both worlds are able to spawn Chlorophyte ore.

And both altars are the same.
