Having options is always a nice thing and having a trailer with a 2" receiver on the front give you just that. I personally prefer a standard 2" ball or Max-Coupler which is why they are the only options on the trailers I make. A 2" ball will articulate quite a bit and can be used on most trailers not planning on seeing real "trail use"..... but one washed out creek crossing and you will find the limit of a standard ball very quickly. A lot of times, "overlanding" means "over-prepared" and you dont want to cut your trip short due to a failure.
While there is NOTHING wrong with a pintle hitch, they do make more noise(especially on light offroad trailers).
As with anything, the more moving parts something has, the more maintenance it requires. Please check your equipment regularly and dont forget safety chains.
