Mashiroiro Symphony was seriously terrible. I dunno how the original VN is since translations have been on and off (current one is 93% translated common route, but hasn't updated in half a year), but the series is crap...at least it has decent art.
White Album 2 does have the benefit of being adapted from a "kinetic novel," which has no choices and therefore no branching story. Most VN adaptions are of ones with multiple routes and they try to shove every route in somehow.
That makes me a bit worried about Grisaia no Kajitsu's forthcoming adpation, but it's the first in a trilogy and the latter stories sort of shoehorn all of the routes into one from what I hear (only the first VN has been translated so far)
