I believe outputs from ArcGIS are infinitely more attractive and easier to create than outputs from MapInfo. However I find it exceedingly frustrating that labelling is rigid with very little room for alteration, even when using the Maplex extension. MapInfo offers the capability to pick up and move labels and then delete any custom labels that have been produced. I believe this function is very useful and combined with the edit annotations in ArcGIS would be very useful to many users.
Of course such a feature may exist as an add-on or in another format. If so please correct me and point me in the right direction!
