In particular, keep in mind that a project going through Kickstarter now will likely not ship for at least 6 months, if not a year or two. (Some exceptions exist, such as products that have already done the work and just need to scale, but even then they usually take months after funding completes to sort out the logistics.)
So if you can ship within a week or so, long before the project finishes funding, you'll take advantage of the interest.
Your other alternative would be to decide that you care more about seeing the idea succeed than you do about winning by yourself. You could contact the Kickstarter project team, tell them that you've been working on this for six months, and tell them you'd like to join forces to bring a product to market faster. If they're just raising funds and don't already have the details worked out that you have, they'll likely welcome the help, and you might welcome the funding, interest, and marketing.
Let's face it, never is also high on the probability scale.

What makes them better/different or noticeable? Marketing. Take a look at the web hosting industry. There are literally thousands and thousands of web hosting companies all offering (nearly*) the same thing. They differentiate by reputation and marketing. Ask any small business owner if they have a website, then ask them have they heard of AWS? I bet they won't. They'll be use Joe Host down the street from him or GoDaddy or won't have a clue and they have a "web person" to take care of that.
A product idea only gets you so far. Now you need to master how to get people to find it, tell them they need it and get them to sign up by hopefully providing you their credit card for X service/product. Your journey is just starting.
