What Works Best for Landing Pages?

I have used several different styles of landing pages to create conversions and opt ins, but I want to know from other warriors on the forum, what exactly do you feel is the strongest landing page, and why?

Is it...

A Squeeze Page?
Pros: Allows follow up and maximizes profit
Builds a relationship by offering free content and a conversation
Increases conversions by grabbing the people who need time to think later on
Allows you to sell just about anything on the back end

Cons: Poorly optimized for SEO. Google hates simple sites with no links
Can sometimes be difficult to offer all information on one simple page
Offers no choice to the visitor

A Review Page?
Pros: Creates the illusion of choice while providing value. (Which affiliate link would you like to make me money with, mister visitor?)
Gives people confirmation they need to purchase a product by comparing it to other products.
Creates a sense of honesty. You can give each product an honest review and let people buy which ever one they think is best.
Diversifies your affiliate programs. If one program shuts down, you continue to make money off of the others.

Cons: Does not offer any follow up except from pop over opt ins or sidebar opt ins, usually minimal.
Takes the most research to promote and refine. You have to be familiar with multiple products, unless you are doing a single product review.
Can often leave a customer confused by too many options due to this, and when confused, often times the easiest choice to make is to leave.

A Sales Page?
Pros: Very active in hard selling the visitor. These sites are exciting and often create mass hysteria when they go viral.
Are long and usually answer every possible objection with a rebuttal.
Can basically roll out the red carpet for anyone who arrives at one of these.

Cons: Often times very sudden as a landing page, like third base on the first date. (Perhaps your customer would like to get to know you a little bit first?)
Not very effective at capturing e-mails
Can be seen as spammy or untrustworthy, especially if a visitor does not know you or hasn't seen your site ever before.

A Blog?
Pros: Constantly updated, blogs are like living things rather than static sites, so people see them as relevant and interesting.
They get ranked extremely well in SERPs allowing you to get more traffic.
They are used to express ideas and give people information while building a community of followers and interested listeners to sell products to.

Cons: Can sometimes create too much choice for visitors. Which blog post is most relevant, and how do I get your free report again?
Requires regular updates to maintain conversions. This makes it difficult to automate a blog. (Unless of course it's a flog).
Requires the most content to be effective.

So warriors, what is the most effective landing page type for you, and why?
