I have no idea how the 2 compare - but do yourself a favor; save up some money to buy a real scanner, not these little toys (of course, everyone has their own opinion as to what makes a 'real scanner' - but to be frank, to me, neither of these are...)
Make yourself familiar with our wiki which has a ton of information on numerous different models, not just from RS, but GRE and Uniden as well. Just hit 'wiki' in the top blue toolbar.
