ClassicUO does an excellent job modernizing the original UO Client while maintaining the original feel and features of the classic client.
TazUO tries to add features to CUO that were not in the original client but can be argued are an improvement.
TazUO is a modified version of ClassicUO, meaning your favorite assistants and favorite features of ClassicUO are still available!
There are too many to list, but the most popular features here would be:
Totally customizable tooltips, change color and change property names/formatting!
Bring your own fonts!
There are far more features than listed here, please glance over the wiki to see if anything speaks to you!
