Dear Binh,
It isn't clear what you would like to switch from and why. If you have a specific application and would like to know the best solution for what you are trying to do, we have many knowledgable people that can help you in our sales department. Or if you have specific questions regarding pro's and con's for the application you are attempting to accomplish feel free to email us or give us a call.
Best Regards,
Amy Hindman
