If it's for the sake of backlinks, I would also go for the "1 from 500 Domains". Of course, make sure those domains are of good quality, not just some random sites related with yours, and the placing of links must be properly done.
Most webmasters would rather link build to get their site/s on top of the SERP, that way they can get more organic traffic and sales, rather than linking to some related sites that gives poor traffic, and worst no sales

But as AWALL19 said, it still depends on what you're targeting.
