Larroca does better with what used to be known as "Marvel-style" scripting (i.e. writers gives artist plot, artist handles layouts/pacing/etc., writer scripts based on drawn plot). All Marvel books are now done full-script (i.e. writer drafts detailed plot and script including pacing and specific layouts, artist draws only what writer tells them to).
Compare Larroca's current Uncanny X-Men with his work on X-Treme X-Men back in the mid-2000s. It's the difference between night and day.
