In my opinion, training is generally more important than experience.

A new pilot with little experience can be trained to proficiency. The military does this all the time. Of course, the military has the money to throw at training, so they can do that.

Private pilots usually don't have the money to throw at training like the military and even if they did, the same level of training found in the military usually can't be bought. With few exceptions.

An experienced pilot who has not received proper and/or recent training may be ill equipped to handle situations that stray beyond routine.

Experienced pilots generally have better judgement than newer pilots, unless the newer pilots have been trained in what constitutes good judgement.

Of course, this philosophy extends to any career field. Not just aviation.
