both superwinch and smitty are built in china, but the superwinch is supposed to be the best built chinese winch.
I had a smitty x20 with synthetic and it worked the two times I needed it to. Their winches have really gotten a lot better through the years, especially the waterproof ones. I believe the TG winch is a rebranded smitty. If you're on a budget, and you'll keep your winch in good shape, I don't see why a smitty wouldn't do the trick for you. Is a warn more reliable? Probably, but even warns aren't 100% reliable all the time, they need love too. I'd pick something that's rated for submersion underwater and is completely sealed. That should keep salt, mud, and snow out of it, which should keep it running reliable for a long time.
When (if) it ever comes time to tub, I'd be happy to come over and help for a bit. I've never tubbed a tundra, but I've done 3 tacomas, a 3rd gen 4runner, and a '79 pickup. I don't imagine a tundra would be much different. It's a bit of a pain, (especially if you're not very good at welding sheet metal) but the results are well worth it. Here's my taco on 35s with 2" lift (though the 35s fit with zero lift).
