Nutritionally there is nothing wrong with either. The jarred stuff is made with fresh produce and processed very quickly, sealed in the jar without additives. And as for the homemade stuff, for a baby who is old enough for solids, the food doesn't need to be blended THAT smooth, even fork mashed would be fine.
I mostly used homemade food for my kids, for two reasons: I didn't see the need for them to start on only ultra-fine texture semi-fluid stuff, and I did want them to develop a taste for my kind of cooking. I don't know about you, but I don't usually eat brown beans mixed with apple sauce for dinner, so I didn't see the point in getting them used to those flavors.
I didn't do full on baby led weaning, but I did offer a combination of purees and finger foods right from the start. The idea of worrying about a tiny bit of fiber is funny after having seen a 6 month old happily gnawing on whole cooked baby carrots and green beans.
