There isn't a "correct" answerr to your question.
I think it depends a lot on the type of music that you play and sound you want.
The dread will give you slower response when you pick a note and long sustain.
Depending on the song, I don't normally like that for solo fingerstyle, but generally I do like more sustain for accompaniment of a vocal.
For solo fingerstyle I like smaller bodies. You get faster response and less sustain. Both of these help to keep the notes separated. I also prefer 1-3/4 inch nut spacing to make left hand manuvering easier for me.
Whether you use finger picks, finger nails, or the flesh will also effect the results. If you use flesh, you may have difficulty getting enough volume from a guitar with a stiff top.
Ultimately, I think it comes down to the individual guitar, not a generalization about body shape. You may have or find a dread or jumbo with a very responsive top that is a dream to fingerpick.
The other factor is simply the size. For some, a dread or jumbo is just physically uncomfortable to play with your hand down near the strings and palm on the bridge (for Travis style).
