To add to what Dave has said. I found that having no control over the relative size and placement of the blocks when using xBlocks made it hard to see what was happening, making the design write-only and hard to debug.
Generating scipts can be tedious though. The mdl2m.m script in the casper_library folder will grovel through a model and generate an associated script which can help save time and effort in this regard.
