Are there certain types of blocks in Minecraft that can generate ice faster in a snow biome, or is it really completely irrelevant?
Minecraft experts are in demand.
No there are no blocks that can do that but you could put tickspeed up
I do not understand your question completely.
But if you think that all modifications of ice (normal, packed, blue, etc.) are created in the world generation, then the block types don't matter at all.
The same applies to the "artificial" creation of ice.
The type of block has no influence on the generation of ice, but ice is only ever generated on solid blocks / ice blocks adjacent. This can be used to build a faster generator such as the 3 https://technik-de.gamepedia.com/Eisgenerator_(Redstone variant)
