Critique Me

I have chosen to create a brand identity for a radically new customer reward scheme for my elective brief.

Target Audience: Web savvy, familiar with earning rewards based on what they spend there time and money on. I am going for a more high end/mainstream commercial target.

The Major Product/Brand: A loyalty card where customers can gain points by using there card, join groups on the website to gain extra points etc.

First logo: Merjing Rings
This logo represents two things merging together, as two different groups merge together for points in the loyalty card game. Thought of other things that merge together (Boy + Girl) Cyan+ Magenta.

Second Logo: Merj initiative
This logo came from combining different triangles, it creates the letter M, and what I think is a clear solid logo.

Third Logo: Merjiangle
Merged shapes. Creates a almost 3d look, and movement. It represents what gets put in, comes back around. Different groups, and connection.

Fourth Logo: Merjic
The initial design I had was very cubic, but had nothing special to it. This one, has an odd 3D look, where you can create different feelings to it, a button, a cube, a jewel (for treasure). Web savvy audience, button, points, and group.

I am so stuck on picking the right logo, which one do you guys like the best? I have already spent a long time refining them, but am open to any super cool suggestions! :) Please help! Need to pick one ASAP!
