Scrapebox or SeNuke?

I'm starting my backlink campaign and looking to find the best software on the market. I've heard about Senuke and Scrapebox but not sure how it works and what I should go for.

If I have to choose between Senuke & Scrapebox, which one do you think is better for the money and links building and why?

Sbox Is a swiss knife and senuke is a Nuke
i would suggest you to start off with Sbox as its one time payment and builds some backlinks fast But its getting saturated theses days But IMO it has more uses then what people think it has

I will say to get both... They got different value if you can use it... If limited budget then try scrapebox first, it can help you lot.
