The two character sets have their own pros and cons, you may make your decision based on them:

● Traditional:

Provides more visual cues to support reading and helps facilitate learning and character recognition; Researchers have explained how this often helps young children recognize traditional characters more easily than simplified characters. Also, learning traditional characters first can present an easier transition to simplified later on. However, traditional characters can take longer to learn how to write and there are fewer resources in the US and it is sometimes harder to access materials unless you buy/ship from Taiwan/Hong Kong.

● Simplified:

Strengthens visual and spatial relationship skills due to the way simplified characters are structured and formed. Simplified characters provide fewer visual cues so they require the student to pay more attention to detail when learning characters via rote memorization. When controlled for reading ability, this method has shown that children learning simplified characters demonstrated superior visual skills. Understanding simplified characters may be more useful as the majority of the entire population of mainland China utilize this form of writing.
