O405 and O405G Hispano doors are actually Bode/Masats, as during
that time Masats was in partnership with Bode, hence the doors have
both Bode and Masats logo.
SMC doors are known as SMC, while Transit is the door
type. http://www.smcbusdoors.com.au/index.html
Leyland, Volvo Olympian, B10M and Dennis Trident uses Deans
doors.
Haven't taken a bus with Ventura doors yet, so can't
compare.
Best brand I think it would be Bode. Those on the O405s and
O405G still close tight like on the Citaros.
Worst brand is SMC, those on some of the older buses can't even
close properly. However I think the newer generation ones
(installed on the newer Wrights) with the air release system close
better.
Saw a video of SMB138Y on 961, with the Ventura doors. Seems
that the doors were quieter and more sturdy than Masats. SMC
Transit very funny, got all sorts of patterns, no uniform pattern
unlike Masats... The Bode-Masats doors on the O405s (not those on
the MK2 bendy and Habits) are argubly the best, still close
properly after all these years... So, it seems that the Bode-Masats
doors (O405s and O405G MK1 bendy) and Ventura doors (according to
user Acx1688) are the best of the pack.
