busuu oder babbel - which is better?

Long time ago, I recommended www.babbel.com as an excellent free website, well, the online exercises were (and still are) not so excellent, but there was and is a friendly community of "teachers": People who will correct your texts and answer your questions. FOR FREE.
A while ago, babbel started to restrict most material to those who pay. Not expensive, but I recommend: Get a good book. Or the Themen CD-ROM. Or the other online-stuff I mentioned here: bbc dw goethe STILL THE friendly people are there at babbel and provide help for free. Sometimes me. Seems some people like to play teacher ;)
BUSUU has similar courses, as good and as bad as babbel. And for most you need to pay. But some are free, AND it is even easier and faster to get your work (texts, even audio) corrected for free. I did not find this functions as first, as I did not really do any exercises. But now I have to admit: www.busuu.com is even better than babbel. But try BOTH. (For complex grammar questions babbel might still be the better place to ask, but maybe those questions are asked in busuu at those "groups".) SHARE your experience here in your COMMENTS!
