Petman,
plus:
as Gabe said, PCB always looks neat.
PCB amps are reproducable to a higher degree.
PCB is cheaper, no soldering posts, (ceramic) terminal strips and the like are needed.
PCB is easier to solder, less artistics are reqired

.
PCB: neat software available for documentation.
p2p wiring sounds better.
p2p wiring has way lesser stray capacitances causing oscillations, provided no shorts occur, it is way more newbie-safe.
p2p can have way less soldering joints and way shorter connections.
p2p is harder to foul up on the umteenth resoldering.
minus:
PCB layout can produce an instable circuit, particularly if the circuit has feedback. For the circuit desinger, PCB layout is as tricky as p2p looks concerning oscillations.
PCB: the dielectric (FP4) in inferior to air in any respect.
on a PCB, conductors/routes are closer together and prone to be parallel Hence stray capacitances are higher.
A properly done p2p wiring requires expensive mounting stuff. Particularly the ceramic terminal strips. And, better have a digital camera to document what you did. No neat software available for documentation.
a p2p wiring requires considerable spatial imagnination and thinking to arrive at a servicable structure with short leads and few solder joints. You should know what to do in detail before you start wiring. Figuring out the wiring during wiring creates a mess.
my personal conclusion : p2p is the way to go.
Hinthint:
get your hands on an old faultyTektronix tube oscilloscope and take your time to unsolder all parts in a meditative mood

, Zen style, and let slowly soak the Tektronix staff's mastership into your mind (if you cannot observe the master work, share the space of the master's work

).
After that mental barriers concerning p2p wiring are gone, promised. Been there, done that.
BTW, you'll find a lot of the stuff you slaughtered very usable for your own p2p wiring. Particularly the ceramic terminal strips.
