My Janome has Acufeed and I made sure to get the in-the-ditch Acufeed foot. I LOVE IT!! It's the best of both worlds.
On my little Brother, I had to choose between in-the-ditch foot or a standard walking foot; and for me the in-the-ditch foot gave me better results. I had to wear gloves to help me grip the fabric and help it along more but it looked better than when I used the walking foot.
I'm not the most experienced quilter, though - if you have better fabric-managing skills than I do or are more used to the walking foot you might have different results. Make some potholders and try out each foot and see what works for you!
