You’re not seeing better engines because there aren’t any. We are reaching the limits of physics.
That’s why we are working on alternatives like refueling in space or reusable ships.
The Artemis missions are testing things that we still have a lot of area to improve upon — materials (a huge one), international standards for things like docking ports, computing, radiation safety, and a lot more.
Yeah, RS25/SSME still have a higher specific impulse than any boost stage engine in operation, past or present.
Artemis II doesn’t have any docking hardware since it won’t have anything to dock with. And Artemis in general is just using the IDSS used on the ISS and by Dragon and Starliner, nothing new being discovered or tested there.

Sharing because this seems to capture the je ne sais quoi that seems off about Artemis for me.
