I found Deans easier to put together than TRX connectors.....
But yes, definatley stick with genuine Deans. The knock-offs often don't fit together well. I have a Deans (knock-off) to servo style plug adapter to charge the RX pack in my nitro buggy, and it is SOOO tight, I'm worried about tearing the wire any time I need to remove it. Any of my genuine deans to deans connections are super smooth, and I've NEVER had one pull apart unless I want it to.
