If your BMW dealer is also a Dinan, that would be the best and safest IMO. Do not let the modest gains in HP and TQ of the Dinan dissuade you. Adding that to the existing is very noticeable. IF dealer does the install - than any issues will be handled between Dinan and your dealer and BMW. DIY and you become the middle man. Is that worth the $165 dealer installation cost...you decide?
All the others, while customizable and providing more power, any issues will be on you and you alone. If the car is out of warranty, then it makes no difference. However, there are instances where engines grenade, seize or otherwise malfunction during the first 4 years or covered miles. Car computer will show a tuner was on the car whether or not you remove it or not. BMW will refuse to fix. $20K for a new motor. You decide.......
