WHat i can tell you is out of the three, i felt the 2.1 has the most linear feel. WHen i drove a few Tekin's with Cyclones, there was an initial "lag" if lack of a better word, then the Boost of the Tekin would kick in and have gobs of power. The LRP was smoother than the Tekin, and had decent power mid and top. Both ESC's are very good in my opinion. Even though i am biased towards Speedpassion, i have to honestly admit i like my 2.1 much better. The Linear powerband is a must for me. I like feeling the input of the trigger with out the "lag" the Tekin does. I also like the fact that with Medium settings, it is up to par with both Tekin and LRP. I ran Max boost this weekend in RCGT and i do have to say, hands down i love my 2.1. Very powerful and with the new 52* software, we get no lag or no cogging at all.

It really comes down to preference. A lot of local racers here in Cali love the Boosted feel so the lag isn't an issue. For me, it has to be smooth.
