I wasn't so sure which version of ipad 2 you wanted cause there's the wifi, 3g n the cdma version but i tend to favour anything with android these days, mainly for the upgradability so i would pick the galaxy tab.
Then again am biased,so head over to www.gsmarena.com and look for the "compare" tab button and then just search your two tablets and the site will list them both side by side according to their spec's then you can make your more informed choice.
