My barbell exercises across the week are Front Squats, Hip thrusts, deadlifts, power clean, OHP and bench. Of those only deadlifts and power cleans do I use clips. The rest I don't both be able to dump if required and as a means of seeing if I'm not keeping balanced across sides (the latter in general stopping the former).Benching with clips on the bar is dumb as f**k. Even worse if youre benching by yourself.
The plates wont move with the caveat if you are executing the movement correctly and using too many plates on each side.
By that I mean if youre benching 40kgs weights on each side of the bar, use 2*20kgs, if you start doing sh*t like using 4*10kg plates, its possible for the plates to slide. However if it is sliding its likely because you are not in control of the barbell, that being the case you shouldnt be lifting that much weight in the first place.
Ive helped a few kids benching at the gym, who hit failure and have the barbell trapped on them. Its not a big issue as at worse its just 1*20kg plate and I tell them to not have safeties so that they can slide it off if they hit failure.
Dont laugh, I actually use clips for my bench. Thats only because I do the OHP next and need clips and all the good ones are gone quickly.
However, I have safety bars in place, so failure just means it lands on the safety bars.
