I agree with everyone. It is on a kid to kid basis I think really.
My son is 17 with AS and has been mainstreamed since Kindergarten.
There have been alot of good points and alot of bad points. You do have to educate yourself. Learn your rights with an IEP.
My son also got pulled out in Elementary school for OT, PT, Speech. He didnt need them after 5th grade. He has always had an aide. She has him and another boy. Although he probably doesnt need her anymore she has been with him since 5th grade.
I think things are ALOT better. Teacher are more educated on Autism and AS then before. My district has an inservice every year to go over it again with teachers.
You have to go in there and fight for what your child needs and deserves. Only you know your child best and will know if she is doing OK or not in the type of setting you have her in.
Good luck in what ever choice you make.
