Recommended word count for backlink articles?

Recommended word count for backlink articles?
I've been building back links for about 2 months now and usually stick to 450-500 words at minimum nothing less than 450 words. The biggest article I've created was made around 1,200. What's the recommended word count you guys believe is good enough to be seen as actual good content?
I'll give you two examples:

list of top ptc sites
list of top ptp sites

+++++++++++++++

1) Site with 300 words, having winning numbers for lottery, for small $$
2) Site with 3,000 words, having only great content, without any numbers.

Now, let's think - which site become popular in short time and which site will receive natural backlinks.
Be SURE, that it will be the first site, even if:

- there is no https
- load time is high
- no responsive design
- content is poor
- design if poor
- etc

Value for user will matter 100x more, than content length.
Checked and confirmed.
