I am no expert on the Javelin, it does appear to work well and I know it has the two methods of attack.
That being said I would think that the closer ranges that must be dealt with in urban settings would lend itself to the Panzerfaust 3.
I heard Germany sent 400, I would think they are going to need a lot more.

There are YouTube videos on the Javelin. It has a 94% success kill ratio on tanks. Fire and forget technology. These and Stingers are amazing pieces of shoulder mounted hardware.
The minimum direct fire range of a Javelin is a little over 200 feet. With soft launch and fire and forget, it is less likely to give away the position of the firer — an important consideration for survival. It is an excellent weapon, a good friend for the infantryman to have along no matter whether he is out on the town or on a stroll in the countryside.
You can direct fire a Javelin with the wet launch. Range in excess of 2000 meters...double what it replaced...the Dragon ATGM
