Taiga

Pros:
easy to understand bug reporting section
Easy to understand in general
nice layout
has a wiki section
import stuff from old projects
priority list (wishlist-critcal)

Cons:
don’t know what it means by “sprints”

Trello

Pros:
easy to understand layout
priority list

Cons:
Not more pros
Nothing is really pre-made like with Taiga, so Taiga saves more time

Freedcamp

Pros:
Easy to understand layout
Calendar
Priority list (low-high)

Cons:
Almost everything is on one tab, so it’s less organized than Taiga

What I am going to use:

I’m going to be using Taiga because I like the layout the best and it just seems easier to use for me. I like that it uses different tabs instead of one giant mess on one page.
