I like the wide, flat shoe Timney uses better but can't otherwise tell much difference.
I suspect some shooters are better at adjusting triggers than others, especially those who've dinked with many rifle triggers for a long time.
But despite not being able to tell much difference between the pull of TTs and Timneys (or a Walker Remington trigger) totally understand how many find TTs easier to adjust. Though for me that's not enough to spend a lot of time and money replacing triggers that already work the way I want 'em to.
