A 1/4" hex drive (I like Stahlwille, get them from TBS-Aachen tools at half US prices or watch ebay) with matching bits fits better in tight spaces without the added length from protruding square drive plus bit socket, and quality bits (I like Wiha) cost much less than nice hex bit sockets (Snapon).
1/4" non-ratcheting hex drives fit even more spots.
