Every crystallizaable compound has a distinct crystal shape and I would think that would not vary between solvents of crystallization.
That is completely wrong. Check any source that has information on crystal type -- it usually says "forms <shape> from crystallization in <solvent(s)>".. each solvent or combination of solvents can form different crystalline structures.
