It will be fine, there's virtually no difference in service to regular cityhopper, apart from the crew not speaking Dutch.

German Airways has very generous seat pitch in C, and still pretty good in Y.

Eastern Airways does not have particularly good seat pitch even in C. And the three aircraft used for the wetlease have different seat layout, which leads to your seat assignment often changing at short notice (I do have 100% success rate maintaining my exit row choice).
