I have had both vinyl and canvass tops on my MGA(s) over the years.

My first was a black vinyl top from J.C Whitney in the late 60's.  It was 
surprisingly easy to install in about two hours with all fasteners 
pre-installed and full instructions included, and it fit fine.  It seemed 
to stretch some in the first couple of months of serious use after 
instllation, and I had to detach the front and retension it once, after 
which it was okay.  If you leave them stored in the lowered and relaxed 
position for an extended period of time they might shrink to the point of 
being nearly impossible to erect and attach properly.

My next new one was a tan canvas top from Moss Motors, installed with my 
current MGA's first restoration in 1986.  That too was easy enough to 
install, but the bottom fasteners came in a separate parts kit and had to 
be installed in the fabric.  The canvas held up quite well with serious use 
for 12 years and 124,000 miles.  I only changed it then because the car was 
repainted and got new carpet and tonneau cover, so the top looked a little 
fadded and soiled by comparison.  What I like most about the canvas top is 
that it is effectively self tensioning.  If it stretches out a bit with 
some extended high speed driving, just wet it down with a hose (or drive it 
in the rain) and let it dry, and it shrinks right back to a nice snug 
fit.  If it has shrunken while being stored in the lowered position, the 
same applies, just get it wet and it will stretch a bit, and it will dry to 
the proper snug fit.  It always fit well regardless of age or use or 
weather conditions, and was always easy to work with, even when cold (and I 
have put it up or down in sub freezing temperatures, often even).

So the "recent" replacement was of course another tan canvass top.  This 
one is a Stayfast cloth top from Moss Motors, supposed to be more durable 
and less suseptible to fading from exposure to the elements.  And I gotta 
agree.  After five driving seasons and another 55,000 miles this one is in 
very nice condition with almost no noticeable fading, a good investment for 
a high mileage driver.  $.02

The new tops now are usually delivered with no installation instructions, 
mostly a liability and warrantee thing I think.  The idea is that the party 
doing the installation will be liable for the quality of the job and the 
cost of the material if it happens to get screwed up.  Remember, the seller 
did not tell you how to do it wrong (what wonderful logic).  But have no 
fear, as it can still be a DIY job.  Check here for installation of 
Lift-The-Dot fasteners and tonneau cover and the MGA top:

The MGB top installation will be a bit different, mostly because of the 
steel front header rail requiring some rivets rather than tacks or staples.

My money is on canvas for the durability and low maintainance.
