Advantages:
more effective at removing shorter, coarser hairs
Removes the whole of the hair (outer root sheath etc)- providing correct technique used.The fact that you do smaller areas at a time means the hair is removed effectively and efficiently.Skin feels silky smooth afterwards
Less uncomfortable
No residue is left on the skin- no getting your undies stuck to your skin!
Disadvantages- tbh there arent any (imo),it may be slightly more time consuming, but the advantages far outweigh this if you percieve it to be a disadvantage. Clients who have experienced a decent hard wax (such as peron rigot or reference) that has been used correctly do not go back to strip waxing for intimate areas or facial waxing.
