The blue card on Aegean is worth even less than FTL with Lufthansa. The problem with the Star Silver level is that benefits are largely confined to the "home" airline. FTL will give you LH business lounge access but not in any other carriers lounges.
However, things change once you get to the Star Gold level, since this is governed by reciprical Star Alliance rules. An Aegean gold card will admit you to all Star Alliance gold lounges, like the LH SEN lounges, the United clubs, and so on. For this card on Aegean you need 20,000 miles in 12 months. On LH you need 100,000. Therein lies the beauty of Aegean. Do note however, that to make this difficult, not all flights credit to all schemes with the same mileage levels, so look before you book.
Your B class ticket, when credited to Aegean, will give you 150% intercontinental, 1250 miles flat Europe and 950 miles flat German domestic. So, pretty much the same as LH. I would credit Aegean, where the award levels are lower. (eg. TATL J 90,000 miles instead of 105,000 with LH, TATL F 120,000 instead of 170,000 with LH)
