I, too, have 10-month old twins (mine are girls though). Neither of them is feeding herself. In fact, they don't seem to like foods with much texture. I read that giving them foods that they really like is the best way to go about getting them started with feeding themselves. So I've tried with chunks of banana and green beans--we're starting with that. They don't put the food in their mouths though, they just play and I end up feeding it to them. They typically take a few bites and then sort of gag on the food--like they just realized they need to chew. It's been slow going.
As for the bottle, I've started feeding them their bottles while they sit in their highchairs. (It was my husband's idea!) That way it's becoming more about eating than about cuddling. They're starting to put their hands on the bottle and, usually, when they're finished, they like to play with the bottle--examine it, turn it up-side down, get it all checked out.
And as a side note, I think it's totally normal to compare the twins--I know we shouldn't, but it's natural. Just like moms of single babies compare their kids to their friends' kids. We just have them in the same house :)
