"and the DK2 honestly looks murky overall." << Must not have the same DK2 I have. Nothing murky about the imagery. Amazing contrast, vivid colors. Now if by murky you mean pixel resolution... it's not a 1440p monitor. But a 1440p monitor gives you Elite in miniature, so of course it looks great. Except as you recognise; it's flat without VR. It's actually flat and cartoonish.
The level of immersion is easy to explain; VR gives you life size 3d visuals. Everything looks solid to the point where you feel like you can touch it.
"Buy the Vive (I think it's the best choice for the next 2 year VR product cycle by far). Then assess what you want to spend to get yourself sorted." - Now you're just giving him heavily biased and subjective misinformation.
1: We have no idea of Vive pricing. So you could be telling him to buy a HMD costing $600 or $1500.
2: HTC is a company with some troubles and their future isn't certain at the moment.
3: Journalists from CES who spent time on Vive and Oculus were of the opinion that CV1 had better image quality, Vive had taller FOV, Vive had more noticable screen door and light reflections across the lenses on high contrast scenes.

Your description of Oculus DK2 as "murky" is just false and inaccurate information.
I would say that Vive Pre is a wait and see product. Wait and see pricing and wait and see if it launches for pre-order.
Oculus has a proven track record and Palmer is the one leading this VR revolution.
Vive Pre could turn out to be a great product or it could turn out to be mediocre or a disaster.
