There are some really cool surface mount IDC things too, and push-in terminators for solid wire.

Solid wire through holes is OK if the wire is never going to flex. Otherwise the stranded wire lapped to surface mount pads, or soldered into through holes, with a big blob of hot glue or epoxy for maybe-sorta "strain relief" is a great pet peeve of mine - it's ugly and it breaks.

Never had a problem with Molex, myself.

It's the .154" Molex stuff that tends to melt after 20 years spontaneously. Not sure what plating they use bit it turns into a power dissipating resistor after a bit which is not good when you're shoving a few amps through it.

Molex is great if you get the reflow-compatible models. Their older lines with the non-updated parts do have some issues at high temperatures. If you really care, look for glow wire tested parts. Or just, y'know, keep your iron away from them and buy spares for when you don't....
