Which domain should I pick for Amazon Affiliate website

I am in the market for a new domain.

I am between the following options.

thebestxxxxxxxxxxx TLD (c_o M)
reviewxxxxxxxxxxx TLD (c_o M)
xxxxxxxxxxxreviews TLD (c_o M)
xxxxxxxxxxxsreview TLD (c_o M)<- same as above but item reviewed is plural.

I'm aware it's all about content but I still want a good domain. The x's represent what I will be reviewing and are the exact length so you get an idea of what the domain will look like.

Any and all suggestions will be greatly appreciated. Thank you for your time.

Get all of them, run multiple sites, dominate the rankings.

Looks like you can take the top 4 spots to me.

Good Luck

Did you choose these domains around specific, yet different keywords? Then as Snort said, get all of them. But it seems like you're looking to dominate the rankings for a specific keywords with several domains. I wouldn't recommend that.

If you want to start with one then go for XXXXXXXXreview LTD because people usually search in that term

I would go for 3 or 4. The singular or plural, which of them is getting the highest search? Go for it.
And to be honest, the domain does not all that matter, but the links and articles.
