Now I have to decide for a new replacement crown whether to go for metal
crown again or switch to porcelain.

My question:

What is typical life of a metal crown on molar?
What is a downside(s) of porcelain(PFM), cosmetic aspect aside?
Any suggestion for choosing type of crown?

Sounds like a pre-fab stainless steel job. Chewing through one
of them in a year or two is not such a tough job for many.

I had metal crown on molar(#31)but it lasted about ten years. A part of
the top surface area was removed and cement underneath was exposed. The
broken crown was replaced with again a metal crown. This time it lasted
only one year. The damage was done in the same way as the previous one.
I chose metal crown because the both dentists who did the first one and
second one recommended metal crowns.

I still keep the removed crown which lasted 10 years. It really looks
"worn out" and appears badly deformed from the original shape. It looks
as though the opposing porcelain bridge struck hard on the metal crown
which appears softer than porcelain so that it yielded to the impact by
deforming itself.

I have gold crowns that have lasted 30+ years. I wore holes through a
couple of those because I clench and grind my teeth.

It needed to be repeated

What could possibly help reduce the damage....mmmm.....I don't know...
an NTI!?!?

It sounds as though it might have been a cheap stainless steel crown.
We call those "temporary."

But even a cast metal crown (much better than stainless steel pre-
formed) can eventually be worn through by harsh contact from an
opposing porcelain bridge.

Generally I like to make a crown of a material similar to that which
it's going to occlude against (bite against).

So if there are no other confounding factors, generally if the tooth
is going to bite against a porcelain bridge, I like to place a
porcelain crown to match.

How can I make sure that I get a quality crown whether it is metalic
or porcelain? Does it entirely depended upon a dentist I go to? Is
there anything I can do to help getting better crown?

Not easy.  Amatus can place a crown or inlay in a day (one long visit
with a break) but most of us send impressions to a lab, so it will
require multiple visits.  Of course, even here the quality is dependent
on both the dentist and the lab.  The dentist should be able to discuss
the materials to be used.  You should be able to discuss this problem of
chewing through the crowns, and formulate with your dentist a plan to
minimize having this happen again.  For me, unwillingness to discuss
these issues in a respectful and comprehensible manner should be an
automatic disqualifier to using the dentist for your treatment.

Thanks for your suggestion.

I will respectfully disagree and say that chewing does not contribute to
tooth wear.
