You are also bias and believe that everything you own is the best thing since Betty White so there is that. I can link multiple threads from the Cummins forum, Turbo Diesel Register, and other forums of owners saying the same thing I did along with multiple truck review sites stating so in their back to back comparison reviews.
Neither of the Ram transmission offerings are that great in regards to speed of shifting and shift strategy compared to the Allison. The 68RFE is better than the Aisin in this department along with smoothness, but Aisin can handle more weight, has a PTO, and is more durable than the 68RFE. It is what it is, and it ain't what it ain't.
But GM no longer uses the Allison tranny, just the Allison name on an inhouse tranny.
While it is true that the transmission isn't built by Allison, it is tuned by Allison. It is that shift strategy tuning that is leaps and bounds ahead of the Aisin and 68RFE. There is hardly any chunkiness and you always feel like you are in the right gear.
Although, you can tune the 68RFE to shift a lot better. My aftermarket transmission tuning made a huge improvement over stock. My stock 68RFE shifted way to early and would put me in 6th as low as 40 mph with the torque converter unlocked leaving you with very little power if you needed to get back on the throttle especially when towing. Tuned, it will not go into 6th until around 61 mph with the TC locked in every shift from 3rd on up in normal mode and 2nd on up in tow/haul. Even without adding any power, it makes a night and day difference in drivability, power delivery, and overall quickness of the truck.
