Still rocking a big-ass bag of XT60's I bought off eBay, like I mentioned on this thread in 2014. Same bag, amazingly! Not sure of their performance relative to Deans (which I used on my R/C cars in the past), but the XT60's with their protected terminals are safer to disconnect without fear of a short, if the system is live.

Truly, anything is better than the cheapo spade or bullet connectors of a typical install. I've also had good success with the XT60 used in power-ground setups, since they hold plenty of current and are polarity-proof, as well as short-proof. I use them to get a quick disconnect on my MS-8, as well as a micro-amp that needs ~12 gauge power.
