Do Tesoro's pick up and read foil as a good targets?
Yes, as long as any detector's Discrimination level is low enough to accept a particular metal target, such as foil, they will. But "foil" is simply a vague reference to some forms of lower-conductive metal that can be found in an assortment of sizes and shapes, and that means a "foil" object can span quite a conductivity range. You can have a small piece of thin, flat foil torn from a wrapper, or a medium or larger piece of foil. It can be a thin sheet of foil, or it can be balled up and thus a bigger and more responsive target in many conditions.
US Coins are generally very consistent, due to the controlled size, metal alloy used, and round shape. As long as they are laying in a flat-to-the-coil orientation, you can get a very consistent audio and visual TID/VDI response from them. 'Foil', as pesky as it is, is more similar to gold jewelry in that it can come in a wide range of sizes, thicknesses, shapes, and even a variance in the alloy make-up. Therefore, it will span its own range of a lower conductivity spectrum, and usually will have very similar responses as gold jewelry.
Just like gold items being very small, such as ear ring studs or small gold pendants, thin to medium to larger and thicker gold chains, dinky baby's rings to a wide range of women's rings and on upo to the generally larger-size men's gold rings, foil will also span a broad range of conductivities. If you don't want it you can increase the Discrimination, thus also missing lower-conductive good jewelry and maybe even US nickel coins and older $1, $2½ and even $5 gold coins, if you crank it too high. Or, the better idea, is to just ignore sites that seem to have a lot of foil trash, or learn some of the subtle audio nuances of the detectors you use because you can
kind-of second guess
some foil.

I've always wanted a v, the tejon seems hard to learn.
The Tejón is a little more complex for some to learn, but for me it really has old-thinking design with the Dual Discrimination like the ancient Fisher 1260X series. I prefer to keep things simple and functional, and while I did once own three Tejón's for evaluation and comparison, there were other Tesoro models that I preferred much more. The Vaquero is 'OK,' but it also has some drawbacks for practical hunting, at least as I look at it.
I do, however, encourage you to get a good Tesoro and a 6" Concentric coil.

I'm thinking about the v, something for coin and jewlery, I have another machine, actually 2 . Not tesoros though.
Your Makro Racer and, I believe, Teknetics Euro-Tek Pro, have their plus points, especially the Makro Racer with the small
'OOR' search coil. But I suggest you shop for one of the Tesoro's that I personally prefer as 'favorites,' and those include the Bandido II, the Bandido II µMAX [size=small](pronounced microMAX)[/size], and you might want a Silver
Sabre µMAX for a turn-on-and-go detector [size=small](preset GB)[/size] or the Eldorado in the [size=small]micro[/size]-housing, if you would like the have the ED-180/zero-Disc. adjustment capability.
Use their stock coils for open areas w/sparse targets, but mount a 6" concentric on any of them and you will have a very handy detector for hunting many places that might hold gold jewelry and other lost desirables.
