TN allows for 3 years per visa and unlimited visa renewals, so as long as you demonstrate that you aren't trying to gain citizenship, the US embassy shouldn't mind.

As a Canadian, I have no interest in becoming a US citizen. On a TN visa you can open bank accounts (including investment), buy cars and real estate and do everything other than start a company. It's incredibly convenient and painless compared to an H1-B.

Most people gunning for H1-Bs want to become US Citizens. Canadians have no such need, we just want to work in the US legally and be able to buy stuff and make investments, all of which you can do easily on a TN.

That's BS. TN doesn't help Canadians with family. Also US CBP can always terminate your TN visa on the border if they "think" you are abusing. H-1B is safer for that reason.

Any visa can be terminated for any reason at the border, no difference there b/w TN and H-1B (IANAL).

Well, it's not really a law, but attorney has suggested that CBP normally don't terminate H-1B at border vs TN as H-1B does have a dual intent, so they can't just say you have an "immigration intention" to deny your visa at border.

And that's definitely an advantage over TN.

Yup, after a few visits back home US immigration officers have asked me variations on if I was planning on returning to Canada. Regardless of my feelings or intent, the answer is "yes, I plan on returning", especially when a guard is explicitly trying to catch you with intent to immigrate.

Canadians have no such need

Really? I know a lot of Canadians with US citizenship.
