You're getting responses from pre-I695. WA car tabs frequently ran over $500 for a newer model back then, now they are less than $50. Every state collects taxes in one way or another, and you'll find that the tax load equates with how much service you get from state government in one way or another. Don't let taxes decide where you live. As far as scenery take a look north of Seattle. Can't be beat! You can cheat on that I-5 rule, just stay west of the mountains..and pay attention to winter flood zones.
That's not to say that, depending on your lifestyle, you cannot find a 'sweetspot' for taxes in one state or another. If you don't own real estate then a state that garners most of it's tax dollars from property taxes is good for you, for example. But for the average citizen of each state it's all pretty even if you look at it in depth. Low tax states offer less in return.
