ELI5: How much (aesthetically) will a child from one sperm vary from another?

In other words, of the millions (billions?) of sperm in the firehouse, how close in appearance would a child conceived between two sperm in the same.....load.....be if 1st and 2nd place to the egg were swapped. Got curious from the sperm over/underproduction ELI5.

There are a variety of factors that would effect the phenotype (physical traits) of a child from sperm to sperm. The most obvious one is of course that they could become either male or female. The next factor is the chromosomes they get from the father. There are 23 sets of chromosomes, two per set. This gives you 2^23 (~9 million) possible chromosome combinations that can be present in the sperm (including the variation of sex). Finally, there is a process called recombination, in which parts of chromosomes in a set will swap, leading to further variation. This gives huge variability  to the inherited traits from a father from sperm to sperm.
