It's similar but in my opinion with every release Microsoft makes their products slightly more unintuitive. This version of Paint is far simpler to view and instantly know what to click to get what you want.
Similar to you, "discoverability" is what irks me about MS trend recently.
As you say, the version you can "view and instantly know" = easy to discover what/how you can do.
A lot of MS stuff recently seems to have forgotten that people need visual cues to "know" what to do.
