What is the most reliable 7200 rpm 2tb hard drive available now?
Thank you in advance for any help.

No one knows.
No one measures that accurately and even if someone
did, you wouldn't be able to buy the drives anymore.

It does not make sense to talk about "most reliable".
They all are not reliable enough to use without backup.
At the same time, they all are pretty reliable at the
monent (if treated well, regulal long SMART selftests,
reasonable cooling, alerting in place, etc.), no lemons
around at this moment AFAIK. That can change at any time
without warning, of course.
Note that for consumer-grade equipment, "pretty reliable"
means something like 5% failure rate per year and the
manufacturers are not aiming to improve that as it does
not make economic sense.

I notice that on newegg the WD RE4 500 Gig enterprise disk seems the
most reliable WD in there. Do you think the RE4's are overall more
reliable than the Blue's?
I see they have vibration sensing and compensation.

I would think that most drives have vibration sensing.
Look for white rectangular 2-pin shock sensors, usually angled at
45deg or 25deg. You will generally find them at the corners of the
PCB. There may also be unpopulated locations reserved for these
devices.
For example, see the bottom left corner of this Seagate PCB (LHS of
photo):

Here are 3 photos of the same Samsung PCB which show 3 different shock
sensor configurations:

(0 sensors)

sensors)
One shock sensor is located to the right of the SDRAM, while the other
two are at the top, above the square motor controller IC (SH6125B).

Maybe or maybe not. The RE disks may just be used in better
environments, e.g. cooled better and handled better.
The only "enterprise disk" I ever bought was a Seagate ES,
and that was the only DOA disk I ever had as well.

Obviously it was over-tested, to prove it's reliability prior to
shipment!

Indeed! Including a destructive mechanical-shock test. ;-)==)
