What will the clients remember most after seeing your marketing, your creative approach or your product?

حسن طريقة العرض التي تجعله يتمنى لو أنك تعمل معه في شركته

Wowing somebody with the product alone is very very rare.99% of the products out there are generic and commoditised.
There is nothing to go wow about.
Most often people have already seen out products, or the competitior products and have fair bit of expectation of the product.
They will remember your product, its details and data but you cannot make it "memorable" unless you are Steve Jobs and unvieling iPhone4!   You can make it memorable ONLY by the way of approach: establishing rapport, creativeness, utility of meeting and understanding.
Unfortunately, its very tricky thing.

the clients will remember my product ,, if i have good creative approach

The creative approach helps to make the product more attractive and unique and the aim is to bring the clients in (your showroom). Then, the only thing the potential customer remembers is the added value of the product and above all the customer care he/she experiences!

First your approach way and marketing tech..and from these the client will decide to buy if he want,If he don't want he will remember your marketing way (Your attitude and aptitude)

both

At the frist place the customers are attracted with the creative approach of marketing then onward they are retained with us with the quality of the product.

Proper marketng approach can sell your product high , customer always get attrected by  creative  approach with high expectetions so the product should also speak high because todays customer demands high    

I suppose by client you mean customers so I am treating clients as consumers/customers of the product.In recent times it is both the product as well as the communication of how you market that product.
With information and reviews about the product available to consumers at a touch of a button,we cannot camouflage an inferior good with superior marketing clout.
Indeed the clients would definetily remember the creative approach provided it's been done for a quality product.
