I also like Tan Towels and think (for me) they smell the least. I think all of the self tanners have that smell to some degree and I agree that depending on your body chemistry it can/will smell differently.
I like the following:
Tan Towels because I love the easy use of the towels, I get no streaks, easily blends, GREAT for travel and maybe best of all...dries really fast and does not leave any marks on clothing and as long as I wash my hands right away, does not stain hands at all. However there's no way that a 1/2 body towel does 1/2 my body! The 1/2 body towel is dry after I do my chest, arms, neck, face and hands. If I use the full body towel I can add my abdomen and feet-knees. My one complaint is that there is not enough product on the towels. However they do sell a seperate spray that you can apply with the towels and it works good that way. I'm very fair and this gives me a good believeable tan, especially in winter when I only need upper body/face color. Oh, also there is no color to it so you can't see for sure that you got it everywhere, but like I said, I've had no problem with streaks or coverage at all.
For a darker tan when I have more time and want full body coverage I use Xen-tan or Faux-tan lotion. This lotion is DARK and you can see exactly where you put it and you have to rub it in good. Smells like almond to me. You have to put it on with gloves, at night, and sleep in something you don't mind getting dirty. The initial color will wash off when you take a shower in the morning and it leaves a great tan. It lasts about a week for me and is great before I go on vacation (then I take my tan towels to keep it up).
