Well I have Pocket Informat Its Good its colorful its useful i dont know if the other you mention are better but pocket informat is good. One you should know its good but its kinda hard i had to be messing around w/ it over a month to get it its kinda complicated so if your a begginer like you said i would suggest you to get the other ones. i suggest you to try a demo for pocket Informat.
