Which article is used between a "name" and a "tagline" [closed]

Suppose, I am selling a new product named as: "Innob" and there is a tagline followed by it: "___, new breath in (the) town".

Which article shall I use between the name and the tagline ("the" vs "a/an")?
In other words, which is grammatically correct between below 2:

"Innob, the new breath in (the) town"

"Innob, a new breath in (the) town"

[Note: tagline is altered for privacy, however the question remains the same]

Reference- oxforddictionaries.com

the new- Produced, introduced, or discovered recently or now for the first time; not existing before:

"Innob, the new breath in (the) town.

a new- Already existing but seen, experienced, or acquired recently or now for the first time.

"Innob, a new breath in (the) town.

I proffer:

"Innob, the new breath in your town.

Grammatically both are correct, but the meaning is different:

"a new ..." refers to one out of many, whereas
"the new ..." refers to one specific thing, in this case your product which is (hopefully) unique and therefore attractive for customers.

=> for advertising purposes, I'd choose "the new xyz".
