I think the 2 things to consider are:
1. Are you a foodie? Do you enjoy TS restaurants?
I am, and one of the big things I enjoy about Disney is sitting down for a nice meal.
2. Are you comfortable eating alone?
I'm not necessarily, but I've done it. With smart phones, it makes it much easier, as you can keep yourself occupied while waiting.
I've found that when I eat alone (anywhere, not just Disney), they sort of rush me through it. The service is always very fast... they want to flip the table and get a bigger party (ie. bigger tip) in. As a relaxing time, it's been pretty short.
