Can a Judo expert hold his own against a Taekwondo expert?

I am very interested in starting Judo classes for self defense and personal fulfillment. I came across a Taekwondo dojo and I was tempted to go in and check it out. I ended up speaking to the instructor and he told me that Taekwondo one of the most powerful of all the martial arts and that whilst martial arts like Judo, Aikido, Tai Chi and others are effective, an experienced Taekwondo person would most definitely triumph over them. I want to take Judo still because I personally like it but I don’t think this guy is serious at all about martial arts. Can Judo hold its own against any martial art?
