I use mine all the time now. I used to just use it when I was towing my Jeep, but now I just automatically turn it on. I've found that cruising along, I will get less shifting when climbing overpasses and small grades. Without the T/H mode on, the trans will shift frequently; shifting creates heat in an automatic transmission; less shifting=less heat=longer lasting transmission.
I'm actually not a fan of the aggressive engine braking under normal driving conditions though. Like when I'm exiting a freeway and need to coast and slow down gently, as I get slower and slower, the engine braking gets quite aggressive and will cause my rig to jolt as it downshifts. This disruption is quite unnerving while navigating a turn, and could actually be a bit dangerous. It doesn't happen all the time, and I've learned how to mitigate it, but the first few times it was quite annoying.
Other than that one little issue, I prefer to drive the rig with T/H activated in general.
