I like spinners, Netafim Jr to be specific (not easy to find). The top reason is that I fertilize / improve the soil with compost and mulch and the rain provided by the spinner makes it decompose and penetrate over time. But I'm in SoCal with less natural rain than you... Also, I have hard well water and drip gets clogged over time and you can't really see that until the tree tells you and by then it's far too late. In the veggie garden I use drip and inject citric acid to keep it going plus replace about every 2 years, plus it's easier to see there... The thing I don't like about the spinners is that they tend to wet the trunk of the tree... Lots of considerations you have to weigh based on your specific requirements...
