Well... Both kits require drilling and installing updated springs so that part is essentially the same. The Superior kit supplies you with both Gov valves where as the Transgo you need to grind you own valve.There is just is more work with the Transgo to get the same results as you would with the Superior Kit. The Transgo offers a sub kit that allows you to make it a full manual Valve body. Most street / weekend strip racers don't use this.
Don't get me wrong both kits have their good points but lets face it everyone hears about Transgo even B&M has taken a back seat to them. But after years of using Transgo and countless hours of fine tuning them we decided it was time for a change.
Both have excellent Tech departments. Its just a matter of opinion and i personally prefer using the Superior / Fairbanks Kits.
