How does sous vide compare to other cooking methods?

I have a stomach ailment which makes me intolerant to roasted meat and grilled meat. Even though with grilled food most of the fat drips off, you will notice that smaller amounts of fat still fry on the meat surface throughout the grilling process and then drip off. Even if grease is not my problem, I simply cannot eat or roasted or grilled food due to the effects these cooking methods have on the meat e.g. it may be due to the meat being relatively hard. On the other hand I can tolerate soups just fine. Most likely it is because the fat does not fry or the effects water cooking has on the meat and so my stomach isn't irritated.

Anyway I was wondering if I were to try sous vide, would the end meat be just like or similar to the meat in a soup or is it more likely it would be have problems as with grilling/roasting. In sous vide the meat will be in a bag i.e. never make contact with water and stay at low temperatures. Even if this is the case, I would think the heat would still cause fat and juices to drip out and then the meat would be fried in its own juices. Please explain what you think about sous vide compared to grilling, roasting in the respects I have mentioned. Also how different would the cooking result of sous vide be with steaming?
