I live in the Philippines and the standard for electrical outlets for residential areas here isn't that rigid like with Western countries. A lot of houses/apartments here doesn't have a ground terminal in their electrical sockets. The status quo here is that the additional ground terminal is not necessary since most appliances used for homes are already double-insulated and adding it would just incur additional cost. Thus, most outlets here are just wired with live and neutral.
However, to further complicate things, a lot of appliances sold here have plugs that are either flat-pronged (Type-A), or round-pronged (Type-C a.k.a. Europlug). Thus, universal outlets which are compatible with both of those plugs (like this) are also quite common. Although, sockets exclusively for Type-A plugs are more popular here and we just use cheater plugs (like this) for appliances which have Type-C plugs.
Given that, I've noticed that most Type-A sockets in my current residence often lose their grip even after just a few months unlike with Type-C outlets. This got me thinking whether it's better to just replace most of my Type-A sockets with Type-C ones and just use a cheater plug for my devices with Type-A plugs. By design, are receptacles for round-pronged plugs really better than receptacles for flat-pronged outlets in terms of durability? I've read that Type-C plugs adds additional grip to the socket since the pins are not completely parallel unlike with Type-A plugs.
