Ok... Let me be tactful... Eventually, as you progress, you naturally concern about farming now resources to craft more stuff.
Khora and Nekros are two of the best farming Warframes, but the later is significantly easier to get...
Granted, Khora Prime is out, but likely out of reach unless you clear more of the star chart to access more nodes for Void Fissures (this is getting complicated isn't it?).... Otherwise you'll have to trade with the in game currency, Platinum. So.... I recommend no go here. And vanilla Khora is hidden behind a worse RNG than Nekros.
Sooooo... Nekros still has good value for newer players.
Plus, as I mentioned, you can craft craft craft, but you don't have to claim them into your inventory to take up space. You might as well farm for Nekros at Deimos and craft his blueprints, and only claim Nekros when you think you are ready to take him for a spin.
