Preferred Methods of 2+ NPC Conversations

[DylanHollis]

Currently in the midst of writing another conversation sequence involving 4 NPCs - and I've always been curious as to the benefits/drawbacks of any given method. Why one of you may prefer one method over the other etc..

In all my past mods, every NPC has their own Quest associated with their dialogue, and I've jury-rigged them together using the results script of each dialogue topic.
If Bob was to speak after Bill - Bill's topic 'A' would run a (Bobref.Sayto Bill TopicA 1) in the results script - and so on and so forth. Again, each NPC having a quest with their respective topics.

However all of the support pages, the beginner tutorials and tutorial pages never mention this. They always spell out the running of a gamemode script using SayToDone and setting a StartTalking variable, with others recommending a conversation timer script.

Is one objectively more stable or better than the other? I understand my method of using the Results script is a bit messy in the organisation department but is it more liable to fail somewhere down the line?

Any help or insight would be mucho appreciated
