If you're planning to play through the sequel as well, most recruitable NPCs in BG2 have banters and side-quests. That said, creating your own party ensures that you have exactly the skillset you want, and you don't have to create a full party of six, either.
Creating an entire party is not the intended way to play but can be done. Originally this was via the multiplayer mechanics to create a single player multiplayer game but EE makes it much easier. I would advise against it in your first playthrough however for a few reasons: There is no shortage of NPCs to recruit.
