The answer is "It depends". I have students asking me this constantly and I ask:
What's the budget?
What kind of images do you want to make?
Film or Digital?
Mirror or mirrorless?
Many times, I will tell them to buy used and get the better lenses and bodies for what they would pay for a new, less expensive model. It really depends though. If I have a student who says "I want something I can photograph my friends and family with", a low end Nikon D series. If they tell me "I want something I can grow into (which is much more common)", then I might tell them to get a used D700 or if they have the budget a new, higher end Nikon. I generally recommend Nikon's because Canon now has so many different lens lines that many times, students will order via the internet and get the wrong kind of lens for their camera. And while the Z series now has a new line, I can still use my trusty 50mm F1.4 from my Nikon F on a Z body, so much more backward compatibility.
And if a student says "I want something I can go into a studio and shoot great images" I will suggest they look at a used Mamiya 645 or 645-1000s for film and an RB 67 if they want to shoot digital. Having used these and Hasselblads, I see no real difference in the overall image quality between the Mamiya and Hasselblads, and the Mamiya's are half the price.
Anyway, just my take on this question, which is an almost constant at my university. Be well one and all!
Cordially,
