As a software and robotics engineer I really wish we could get rid of these stupid "DuPont" connectors already. I want them gone. They're huge, fall out easily, and hard to keep track of.

JST-EH is my preferred connector for most through hole type stuff. That shit really stays in place after it's plugged in.

JST-EH is great but let's try to avoid JST-SM. It's worse than DuPont! There's no surface mount connector for JS-SM yet for some f'ing reason every LED strip ever uses JST-SM connectors. This makes it impossible to design something like an RGB LED strip controller board without having to solder some wires to the board (with the connector on the other end).

Drives me bonkers.

Much great info about JST connectors, heck the whole website is great:

I nominate Molex SL. 2.54 mm for easy fit on breadboards and such (EH is 2.5 mm), can fit multiple connectors side by side (just like "dupont" connectors), they have latches (molex KK, for example, has no latch) and many variants: wire to wire, wire to board, panel mount, shrouded and unshrouded. And they are pretty cheap and available (from digikey and co).

JST-EH has a 2.5 mm pitch, plus housing, plus orientation. I cannot see where that shall be any smaller than the omnipresent, universal Dupont connectors. Maybe you mean something different with "DuPont".

Fake DuPont/QI/2550 has zero latching whatsoever. Contact lengths vary and housings come with massive plays. Great if you want a free safe breakaway feature, sucks otherwise. Nearly anything else has a latching feature that require a lot more force or deliberation to undo, like ZIF with a latch or a lock flap.

By the way, strictly for home breadboard uses only, when I need a bit more resistance than bare DuPont I wrap it in double sided tape and let the header poke through it. Kind of works.

Molex Micro Lock is the new (old) hot shit.
