It's way too soon to guess if either, both or neither will ever happen, let alone guess which will be first.
The Blue “national” plan is now looking like a smaller version of the Starship plan with depots and multiple tanker flights, refuelling etc. Ie “immensely complex and high risk”. It has a lot of moving parts and lots of tech to develop but across multiple partners. I think at least 8-10 years.
Do the Blue Origin pathfinder landers count?One of Blue's strengths over dynetics was their promise to make two self-funded pathfinder landing attempts in 2024/2025 to mature their tech before the Uncrewed Flight Test of the sustainable lander.

By contrast, the BO architecture appears to use several very different types of hardware.

I have not seen a diagram.

The more I think about it, the more I think that Blue will make it first.

What of their accomplishments so far makes you think they can manage to pull off this complicated deep space system at all, let alone be first?New Shepard really ironed out a lot of doubts for me (hydrogen propulsion, propulsive landings, crew capsule, along with more recent pictures of their BE-7 engine components. While they still have a lot of things that need to be ironed out, like cryogenic fuel and oxidiser transfer, SpaceX shares a lot of those same issues. Blue is going for a less ambitious system with hardware that shares at least some commonality with their previously flown systems. And I didn't even mention the fact that they are partnered with the maker of Orion, which has flown a deep space mission, Boeing, who while I despise, has built cryogenic hydrogen tanks for over 40 years, and Astrobotic, which has the heritage of Masten which has completed more than 600 flights, all in the name of lunar lander development. SpaceX is doing everything themselves, and while they have the immense experience of Falcon 9, and the quick development of Raptor, I'm not sure if these and their quick execution alone will make them first.
Booster doesn’t use hydrogen, NS capsule is not the same as one that will go to orbit so has almost zero value and I am sceptical they can bring much of the learnings from landing NS to the NG stack. Add in they have no orbital experience, no ops experience and are working on maybe 6/7 different projects at the same time.
