Well now I've seen her flatmate DD Angel. Probably unfair to compare as it's really horses for courses but for me... Julia tops it, YMMV.
Both were great punts, best way to describe the differences (for me) was that Julia was all out energetic, Laura more sedate like she was pacing herself for a day's work.
Or to put it another way, after seeing Laura I went shopping. After seeing Julia I went straight home for 3 hours kip as I was knackered.
