Well, hefeweizens have a lot of little quirks that are easily overcome. It depends on whether you are doing AG or not as to how difficult they are to brew. If you are doing an AG, then I recommend a decoction or 2 step infusion mash.
Plus, if you use a lot of wheat, then you are likely to hit a stuck sparge.
Its also easy to over-hop a hefeweizen.
For fermentation, you have to use the right yeast, and they can be touchy. For example, if you ferment them at the wrong temps, you may get an imbalance of banana

/clove flavors that you may not have been working for.
If you can work past these little nuances, then a hefeweizen is not hard to brew.
I say go for it.
