There is a lot of good point being made but end of the day
Personal choice comes into it, driving feel of BD gives me what I need (been refered to as the old LRP Sphere)
Recently was in a race meeting where LRP SXX SS, Tekin and BD we where all of same driving skill there was .1 - .3 between us.
At the weekend in my BD powered TC 17.5 vs Tekin 208 we where matched all the way down the stright so pointing at both "it is that one..."
They are both evenly matched Tekin gives you some flexiblity in that you can change the setup to your liking if you know what you are doing.
BD is just profile driven 1 - 5 with Dynamic timing done for you so always the same feel
The question which one, personally BD as that is what is installed in my rides where as someone will always say Tekin if that is what they drive..
Personal choice.
