I'll take a highly accurate, highly detailed and decent running locomotive from any manufacturer over any command system any day of the week. I don't have a bias against any manufacturer than can meet this requirement.
Features are almost irrelevant to me anymore outside of good running qualities and prototype accuracy. Sound is kind of fun. Command can be fun when it works correctly, but I could take it or leave it. Not a big fan of smoke.
My favorite controller is still the MRC Model 77 Gold top DC hard wired cab controller that has a separate throttle and brake controller with full momentum. Honestly the closest controller that felt to me what it might be like running a real train. When you had the momentum on and had to put the brake into emergency, it still plowed through the rear of the train you missed on the track ahead of it. It just came to a stop sooner than the service or quick service settings.
My opinion of course. Everyone has different preferences. Nothing wrong or right in this hobby.
