Yup, better is in the perception of the beholder ... a few observations to get
things rolling, from a guy who owns two fiberglass and two wooden (one in the
building phase).

Durability:  for the weight, a stitch and glue wooden boat which has been made
into a composite structure (fiberglass/epoxy on inside and outside) is more
durable, more rigid.  How much more durable?  To the point that I do not take
either of my 60 lb glass boats into surf (both are standard layups from
Eddyline -- not Doug Lloyd's brutish type of layup), but have no qualms doing
that with my 15.5 foot,  38 lb   stitch and glue (sng) Pygmy Osprey Std.  Yes,
that's 38 lbs!

Efficiency:  sng boats (not strippers) have many chines, hence some form of
drag will be higher for the same overall hull shape and loading.  If you can
make a stripper with the same lines as an out-of-the-mold glass production
boat, should be same efficiency, all other variables being the same.

Maneuveribility:  same hull shape, same maneuveribility.  A religious war will
ensue about the "value" of hard chines vs. rounded chines.  Pick your own deity
on this one, and duck and cover!

Maintenance:  Epoxy/glass-covered wood boats have about the same needs as
polyester resin/glass boats, except that the latter are usually made with an
integral gel coat which provides the required sacrificial outer layer (UV
protection; abrasion ablation), while wood boats use a layer of varnish for the
UV shield, and sacrifice an outer layer or two of epoxy on abrasion.  Every
couple years or so, you "should" patch and repair the varnish.  I have not, in
four years of occasional use.  Here, YMMV, although if you built it, you can
repair it.

Cost:  nobody can make a decent living producing strippers or sng boats to sell
to willing buyers (unless the buyers have a lot of spare cash).  Strippers and
sng boats are highly labor-intensive, hence, you will be building it yourself. 
Don't calculate your "rate of pay" for the building.  Build a boat because you
like doing it.  Guaranteed to lower your blood pressure 10 points, and to keep
you out of bars for the duration.  That said, a sng boat will dollar out
(ignoring your labor) at about half the cost of an equivalent polyester
resin/glass boat.

Aesthetics:  wood wins.

Political correctness (can't leave that out!):  tradeoff.  Glass boats use up
petrochemicals derived from nonrenewable fossil hydrocarbons.  Wood boats use
up high-quality wood, either from temperate rain forests (cedar strippers) or
tropical rain forests (okume sng boats).  Neither the temperate nor the
tropical rain forests are being "renewed" as fast as they are being used,
though the wood diverted to making wood boats is not the reason.  Surprise!
