The banana style connectors could be fine. ... or might not be?
Personally, I like to stick with manufacturers that I know and who have demonstrated good quality. That's one reason why I use the Amphenol pins and sockets.
One option might be to visit a hobby shop that deals with RC cars and see if they sell one like the SoloGood ones. The shop presumably wouldn't be selling stuff that wasn't reasonably decent quality.

The spade connectors aren't designed to be connected and disconnected more than a few times. I wouldn't use them for an application where you expected to make numerous connection cycles.
