In all the game scripting that I have tried, ChoiceScript is by far the easiest and friendliest for people like me who are visually (ahem) challenged lols. But that is just my opinion and I don’t think the programs for any of the interactive fiction programs was ever intended to be used by the blind or visually challenged. Which is an unintended bonus for the makers of ChoiceScript that they were able to create a program that anyone can technically dabble with ease.
ChoiceScript also has a very active forum unlike some others that I have tried and even if there are some ugh say weird to downright what the heck topics it is monitored so nothing really gets out of hand. Oh and the moderators are very active and easy to ask questions if you’re lost or something. You can post questions about codes that you’re having trouble with and most of the members are willing to give you a hand. Games that are completed can be passed to be a new hosted game so that is also a good thing. That’s all I can thing about the advantages.
If you want to try other programming languages for making multiple-choice games then here are some that I’ve tried; all the programs are simple and easy to use, I am familiar with using the programs, but I still prefer the ChoiceScript over them all.
Quest – Ah, yes, Quest. You don’t need to download anything for this because you can create and play your game using Internet Explorer, Firefox, Chrome, and other browsers that you can think of. This is one of those click and play types which is good (but not me, because I got lost and some text readers has problems reading Quest. Not sure why, but that happened to me.) The documentation is so basic that it feels bland, but on the good side you can mess with it to make it more of your own game book. Oh and you can make any of your games into a mobile app for free.
TADS – I liked this a lot, but the community for this is kinda in the silent mode at times which is frustrating. On the plus side TADS has a feature for the visually impaired users that they can use with the program enabling them to use TADS without any problems. (I liked that really like a lot.) However, this is really suitable for programmers and people who know the strict rules of syntax.
Twine – the thing about Twine is that it has a graphical/visual interface so you can see what you’re doing. (Un-useful for someone like me hahaha.) It also produces HTML-based stories which will require javascript. It has very limited support for basic programming, so you’ll be on your own unless you have some knowledge on javascript because you can add your own HTML and stylesheets to make your game uniquely you. If you have no clue what I just wrote then leave those features alone for you’ll be editing some web pages and I also am not that familiar with it.
The other two I have not tried, but you can try them if you’d like to compare them with all the other programs. Inform 7 and ADRIFT
With all of that I think whatever we prefer to use as a program to create multiple-choice games will come down to what you’re going to be comfortable using. I just liked ChoiceScript better so if you like something else then that is very good for you. 
@Chris_Conley has shared something very informative about Inform 7. So for any of you who would like to try it you can read the post here. And decide if you still want to try it.
