Hi Randy,
Warm welcome to the forum.
Please update your profile to include your county and state. You will get a much better response with a more specific location.
NIX the PVC. You need flexibility in a garden.
I have used both drip systems and soaker hoses as a Landscape Contractor and a home gardener.
I used Poly Drip for my drip systems. Send them photos and a sketch of your garden and they will help you design a system.

They have great battery operated digital timers with a 5 year warranty.
For soaker hoses I prefer the flat hoses rather than the round, black hoses. They are much easier to weave between your plants.
Whether you opt for a drip system or soaker hoses do invest in a timer. Set it to go off in the wee hours of the morning. Before day break.
BTW - most drip systems and soaker hoses use a 1/2" feed line. I always used a 3/4" feed line. Much better water pressure.
Good luck
