I mostly use bullets since I'm a racer but in some of my bashers its a mix of xt60, xt90 and ec5. Some of my mini cars which are lower power have deans.
Depending what power system you're running like brushed or brushless 2s/lower kv, xt60 should be plenty.
Amass XT connectors for the simplicity of soldering/unsoldering and the caps add the final touch.
I also use 4mm & 5mm bullets with heatsink bullet plug grips...
...mainly because of shorty packs. The heatsinks are more for making the bullets easier to remove from battery pack. Your RC10 Semitruck is designed for using shorty packs.
Just like the plethora of imitation T-plugs out there, cheaper versions of XT connectors are out there as well.
