I feel like the difference with Threads is Meta is owned by a much larger threat that can’t be trusted not to use Embrace Extend Extinguish in some evil genius way that ends up working.
Reddit’s owned by some dummy that did a lot of damage to his own platform but isn’t known to be smart enough or have the resources to threaten the fediverse.

There’s new lands, more QoL, new pals. Nothing drastic I’ve noticed from its release state.
Think Minecraft and then Minecraft after like 3-4 updates.
