Which would be better - dowel-joint or biscuit-joint?

Almost always, biscuit.

Biscuits locate in one axis, aren't fussy about the other. Dowels need
you to get _both_ right, which makes them hard work to align and set
up. You can do this, but without custom jigs to do it, it's far slower
than biscuits.

Dowels do have a small advantage in chipboard, as they don't require
such a large slot. In chipboard, smaller biscuits are stronger than
large ones.

If you're biscuiting, use a biscuit jointer and not a router. They're
supposed to be quick, or else pointless - cutting them with a router
isn't.

For a jointer, find a £200 quid one and study the fence design
(adjustable for height and angle). Then buy the £50 copy of it. Don't
buy the fixed plastic fence versions though, as they're awkward to
use. In practice, and when you can, avoid the fence altogether and
just place the pieces flat on the benchtop to align them.
