So I went from Vuse, to ego One, to a sub tank nano in two weeks. Immediately to a subtank mini and Cloupor mini. It was never about chucking clouds, and I wasn't trying to go through juice. I wanted nic with the least amount of juice. After about 3-4 months, now I have a Crown and IVP D2. It makes a ton of vapor and I love it.
The point is, you are skipping straight to some good stuff. It's will be a Lot more than you are used to. But it's really nice. There are a few 75w boxes that are really good. The D2, the Sig 75w TC. It's all you need, and again will be more than you are used to. The others you list are all doing real good right now. You won't waste your money, and you are not going to mess anything up.
TC is the fad right now. I like it, but a bit needs to be ironed out. Mainly wire aterials used. You could get a Crown, and a 75w box, and be in heaven. Get used to it, learn a bit more, and get the TC mod you want. I think within the next 6 months, there will be many more options available that are more capable. This industry is moving at a crazy fast speed. You won't spend a lot either.
I went another route, but right now, the X cube 2 offers a lot for little money. You can do SS coils in TC without sinking a bunch of money into it. Wait to learn a little more before investing in a high dollar mod.
Battery life is wildly subjective. I only use single 18650 mods. I am getting a half to a full 10 work day right now. 65w, and about 6-8 ml a day. It all depends on how much power you use and how much you vape. Someone saying they can go all morning or all day doesn't really tell you much.
Sorry for the book. But you are on a good track. I'm a rookie too. There is a bit of a learning curve to regulated mods. Right now there are a lot of good ones that will be a big step up for not much money. Darn near disposable status. But really good. I buy two for spare and charging. Hope that helps.
