Which MacBook Pro should i choose?

Maybe no one cares about DDR4. You will notice a difference with 16gb over 8gb before you are going to notice DDR3 vs DDR4.

The opposite actually... most people won't be utilizing >8 gigs of ram...If the ram that is actually in use is faster than obviously you'll see a difference. After a certain point there are severe diminishing returns in adding ram to a system since most of it will be unused. The benefit going from 8 to 16 gigs is marginal, except for very specific tasks, most people don't understand this though and stack it on needlessly in the name of future proofing. You'll see better performance from 8 gigs of DDR4 than 16 gigs of DDR3. But DDR4 aside, you'll see little performance gain from 8--> 16 regardless of the speed of the ram. This obviously applies to the 90% that I referenced in my earlier post, there are some people that do very ram intensive tasks.

We'll have to wait and see. RAM speed is getting to the point of diminishing return just like SSD speed. I would bet my net worth you wouldn't notice a system performance increase going from DDR3 to DDR4. Just like you wouldn't notice going from 500mb/s to 700mb/s on your SSD. It's all "benchmark" nut swinging at this point.
