Which is the most satisfying IO connector system, in your opinion?
Do you like a tactile click? Are you a sucker for screws? Or something you can put in any direction? Maybe it's yours or another country's power plugs?
This is sounding more sexual than I intended I think
Worst internal connector by far is dual USB3, the cable is so thick and unwieldly, I always feel like the pressure from trying to bend it is going to rip the header off the board
The few that I've used either require too much force to connect, or are just friction-fit only (like those Neutrik combo XLR + 1/4" receptacles you find on audio interfaces), but I'll take your word for it. XLR looks like it should feel solid.
I dislike the US power plug way more than the Europlug (or compatible sockets like Schuko). It just slides in, only thing holding it in is friction. Also, there is a connection while the contacts are exposed, exposing the user to the risk of shock.
Also, I like DisplayPort more than HDMI, it clicks really nice on insertion and in my opinion pulling it out is also more satisfying.
