there is nothing wrong with that. imo once you know how to splice, having another person splice your rope is like asking another climber to tie your friction hitch. a correct made splice is a correct made splice, they are only done one way, the right way
i have converted a few climbers over by tying a bowline on one end of a spliced rope, connect one end via loopie/krab to a tree and connecting the spliced end to a steal krab to the hitch of a truck and see what breaks first. the splice will win every time
