My boysenberries are thornless and have a fuller (for lack of a better
word) taste than my dewberries. If I were to recommend one on the basis
of taste or ease in cultivating it would have to be the boysenberry. I
grow both next to fences for additional support. But fortunately I have
the room to grow lots of both and my Grandfather's dewberries have a
place here too. Dewberries are best served with vanilla icecream IMHO.

Boysenberry is a variety of dewberry.
Here's how a boysenberry would fit into the class hierarchy for
"bramble" fruits:
Brambles
Blackberries
Trailing (a.k.a. Dewberries)
cultivars: Boysenberries, Marionberries, etc.
Upright (Erect)
Raspberries
Summer Bearing
Fall Bearing (a.k.a. Everbearing)
There are also lots of cultivars of crosses between blackberries and
raspberries, such as Loganberries.
They're all grown roughly the same way; trailing varieties require
support (trellises), whereas upright varieties don't require it as much
(if kept topped off at a fairly low height); two-crop varieties are
pruned differently than one-crop varieties.
