Lot more work to clean the T2 as opposed to the vivi mini Nova tanks,i want the Nova mini.
Yes, but there's more to it than that. The air flow through the device effects the taste, th, ect. For example, the vision stardusts have a very stiff draw (I don't care for them, but some folks do). Long story short, you really need to try them all UNLESS you know what type of draw you like--in which case you can watch some reviews and choose accordingly.
Personally, I've settled in on the smok reduxes. They have a draw very similar to a joye 510 atty (my standard), and, since the coil is fairly close to your mouth, provide a nice warm vape at very low wattage. ( I like around ~5.4 watts). I have four of them, and none of them leak a drop.
Also, if you're going to rewick, then by all means give cotton a try. It's not for everyone, (nothing is. lol) but it's certainly different, and you never know until you try.
