Yamaha's system wins no prize for elegance in the looks and sound department either.
I actually really like Yamaha's mounting system, particularly the YESS mounts. The ball and socket offers great flexibility, and the hex rod means it won't slip or rotate. I have some Yamaha's that have the bracket bolted onto the shell. I've taken it off, filled in the holes, used a suspension mount and used a YESS arm. Still holds great and sounds resonant. I'll take the look of a Yamaha tom arm over a Pearl style tom arm any day. Even on a very expensive, top end Pearl kit, those arms and mounts just look so generic.
