Do you currently fly for an airline? Only interested because you appear to be ignoring the facts as told to you from people who do.
I have worked for several airlines and not one of them has been/is interested in my many hundreds of hours in level D 737/757/767 sims. They want to know how many hours a pilot has in aeroplanes when you apply to them (check out the various application forms that many require you to fill in these days). If they want to know sim time, they will ask in a seperate question to the "how many hours do you have in aeroplanes, broken down into size/ weight" question.
So the point is, put it into your TT if you want (and no-one is denying that it counts toward licence issue), but don't be perceived to be claiming something you don't have. Clearly state what is a/c time and what is sim. The airline representative will then easily be able to subtract your sim time from your TT so that they are happy......and you are happy
The danger is claiming to meet a minimum requirement at application stage only for them to subsequently find that you don't. No prizes for guessing their next move.......
