Benha,
I personally have trouble with hand placement on anything but a medium to high wrist recurve grip. As a result, my accuracy with a longbow stinks. Even after extensive practice. I switched to a recurve and have been VERY happy about it. Now I won't shoot a longbow unless it comes with a medium to high wrist grip. Usually that means a takedown. For me personally, shooting a longbow isn't worth the inconsistency and frustration.
Shoot what you like, are comfortable with and are the most accurate. When it comes to making the shot, all that matters is accuracy and confidence.
****DISCLAIMER*****
I am not in any way saying a recurve is better than a longbow. Just my preference.
