I am looking at getting one of these, but am unsure as to which one. Which is better/ worth the money? Or are they comparable?

 

Similar enough to go by price. I had the JB+ for the N18 engine and it worked great. Had the Sport on the F56 and it also worked great. From scanning the used market in the past, Dinan Sport seems to sell for less, so if you buy one used you will save some cash.

If you need tech support, JB+ company had more responsive help if needed.

 

So which one would say was better, having had experience with both? Which one would you buy again?

 

Different cars, so hard to compare. I'd just buy whichever is cheaper, giving the edge to JB because the company support is more responsive.. Pretty much going to do the same thing most likely for your car.
