For me, I would say glacier biomes and jungle are tied, jungles can stretch on for thousands of blocks and while they offer plenty of wood, they also mask hazards that you would normally be able to spot very clearly without the trees in the way such as cliffs or pit falls, on top of it monsters can spawn or at least not burn if underneath the trees in the dark patches within the jungle, in one of my older worlds I've been caught out by a Creeper because of this, and so has my friend I play with.
Monsters are easy to see in ice biomes, but you also can't find wood there. No wood = no tools or weapons, especially the case if you don't find a village or a chest with tools already in them.
but ice biomes don't generally have ravines nearby, because they exist atop frozen ocean, therefore it is reasonable to assume you won't find a ravine until you find a neighboring land based biome, so there's that to consider.
it's good to have a jungle nearby because of melons, but to try to survive in one on the first night is very dangerous.
