SighIn my veiw, ( having both )
Ego - Nice peace of kit. Used wipe paint off the side but away. Not even broke 1 ball in the 20 odd boxes I've shoot through it.
Speed - Nicer than ego to shoot, Bit more accurate at range. More of a pig to setup. Dose break paint in the breach and barrell.
If I could only keep one. EGO stays
