Reflection on Search Engines, Meta Search Engines & Subject Directories
In my opinion, these all are useful to search latest news, popular games, educational information, media resources, auctions and so on. Among three search engines, subject directories search have quite limited results. It can't show more related websites to ur search topics like search engines.
Although search engines are more useful than subject directories, sometimes it still can't give some rare information because each search engine will search topics typed itself only in its any database. Finally, meta search engines will give u any information that u want to find since it search ur desired "Information" throughout the search engines until it really can't find.
So, i would recommend all to use Meta Search Engines to get what u want to know in various sites as fast as possible.
