Brand doesn’t matter afaik.
They are simple metal parts so they’ll last forever, unlike the plastic ones.
The rubber seals and o-rings are standard parts that can be easily sourced and replaced.
Grease can help seal them, however it also attracts dirt so not ideal.
I tried brass quick connect hose fittings but the ball bearings kept denting the brass and the fit got worse and worse.
I replaced them with some stainless steel quick connect fittings I found on ebay from a power washer supply place. They have held up much better. The main drawbacks are cost and the seal is non standard so you would need to stock up spares/ hope they keep selling them.
