you made a good point but leaving too much details in your brief post its cryptic as well
care to explain as to why you think like that
personally i dont have a problem with either
my main problem is which one should be selected to start with

reusablity of existing knowledge is what i am after the most next to good documentation

i dont want to be in a position where i have to start all over if i want to learn something else later

my questions are like this as i aint familear with either of those.
