in my point of view both are good, let me tell you how?

First, if you have a good amount of money for online marketing and u want result in a short time period so PPC is really good choice for this. But the Cons, is only you can earn or getting traffic that time only, whenver you stopped your Ads, result will stop :)

I personally believe in SEO Bcoz its take a time but give you long time result. :)

So my suggestion is Go with SEO rather then PPC.

Hope this helps :)
