Not quite - in my understanding - with midi clock you have to depend on a
as-close-to-realtime-as-possible behaviour of the midi clock master. Most
software sequencers these days produce considerable jitter on their midi
clock output which is definitely a problem (for instance when I scroll or
zoom in Tracktion the midi clock gets noticeable slower and recovers when I
stop).

IMO with MTC this problem could at least be partially solved as MTC messages
contain absolute time references which could be used to calculate the
current tempo independent from interval in which those message are arriving.
So yes, the MTC slave would run on it's own tempo, but (dependend on the
processing power available) would be able to provide better synchronization
with devices which are not capable of "realtime" sync output (which
conceptually would be any software on a "modern" preemptive multitasking
operation system uncapable of providing realtime scheduling).
