I've used both. For me, distance to pin is key, so I prefer Laser.
I'd recommend Laser for you too - as you don't really play enough away courses to justify the benefits of GPS over Laser.
You will know most distances in your home course anyway, so the focus should be on the shot to the green.
Laser is 'away course ready' too and doesn't require an annual sub - though there are plenty of GPS ones that don't either.
Try GPS on phone out in bounce games - but remember Phone GPS is not allowed in comps.
I disagree with part of your post. The laser is not always course ready if its a blind shot or if you have to clear trees etc.
