Is it best to go to a technical school or through a continuing education program for CNA training?

I've heard that it's best to go to a school rather then one of those private schools that have internet sites that are really cheap but however is it better to go through a technical college or a college with a continuing education program? They have both here. If I went through the technical college it will take 2 quarters and if I went through the college with the continuing education program it will take me about 6 weeks. Does longer mean better? The college with he continuing education program is a real college but this is just through continuing education. Does that mean it's any good? Or would it be better to go through the technical school? Thanks in advanced!
