The big advantage of toluene is that even when it went through an A/B process, it's dry. Ether contains lots of water and has to be dried, toluene will contain much less when you sepatate the phases correctly.
Acetone doesn't make a big difference, since there's only a few percent present (none at the beginning) when you add the acetone washings to the gassing solvent. All those filtrations and washes were done in a sintered glass funnel, adding only enough acetone twice or three times to barely cover all the crystals, stirring it around with a spatula and removing it as completely as possible by drawing air through for a minute or two.
Try it out, works like a charm.
