I have to agree with DreaminGirl that the outcome depends on the model you're converting. That said, Crossdresser is easy to use for a quick conversion but also gives you many options should you like to have more control. Keep in mind that I've only converted from V4 to La Femme so my experience is limited but I've been satisfied with the results and in some cases even footwear, which is not supported, converted well. Here's an example where I converted 3D-Age's Dress Up II for V4. Crossdresser gives you the option of adding handles to skirts for better movement which is a plus.
