Wordpress or Xsitepro for an email sign up site?

Ok, so I have been planing to make a site in a niche I have another site in and use it to build a list. Would have the sign up/squeeze page but also a lot of content pages. Now I want to stop "planing" and start *doing* However I can't seem to decide if I should use wordpress or xsite pro.

For wordpress I was going to go with a smiple 2 column theme (made with artisteer) menu bar under header graphic (home, sign up, about us etc. pages) and side bar for posts. Unfortunately I can't get categories (or archieves) to look the way I want (ie. like on this blog: Articles - Entrepreneurs-Journey.com by Yaro Starak you see all posts in a certain category without the need to click on a category name, anyone knows what plug in would allow me to do this?)

Xsitepro seems like a logical choice here, it's easy to use and gives me a lot of control on how things are displayed. But on the other hand wordpress has plug ins to do just about anything (like split testing squeeze pages) where as xsitepro has what it has and that's it unless you can code.

Blah I am just renting at this point but it's annoying, spent like an hour trying to figure out which way to go (as well as tryign to tweak wordpress lol) and still haven't decided ;( I would appreciate it if anyone could let me know what wp plug in would allow me to display either achieves or categories in a way where you have
Category A:
posts belonging to category a
Category b:
Posts belonging to category b;

Instead of what I get now which is:
category A;
Category b;
Where you have to click on the category (or in case of archieves month's name) to see the posts in it.
