It's definitely not the same. It has taken over a year and probably 1000s of man hours at this point. If you want to see some of the differences you can see here: https://blog.redotengine.org/2026/01/29/redot-lts-26-1-stable/
Unless otherwise stated everything listed is not something in Godot.
A few items:
UID Viewer tool
SoundSmith
MCP for using Ai agents in engine
Gif, Apng, and webP support
More co.ing soon with 26.2 update.
Hope that helps.
