I like the coaster brake because I don't prefer the hand brakes yet for him. Are there any other brand names that I forgot about? Trek, Schwinn...?
Also, is aluminum better than steel or vice versa?

Even if you went for a “bargain” bicycle, I’m sure your son will outgrow it before he wears it out.
So I’d go for price.
That’s great you want a nice bike for you son. But I don’t really have a comment on either. While I have several high end bikes and my two girls ride too, I always bought them cheapo but good 12″, 16″ and 20″ bikes. They just get a couple years of use and they are in great shape when they out grow them anyway. Now that my 10 year old graduated to a 24″ I got her a nicer bike and in a few years she have a high quality bike of her choice.
I’m not saying your choices are bad, they are great. If I were to pick one I’d go for the Trek.
I just find most kids bikes durable – almost any problem with them is directly related to no maintenance being done. BTW all the bikes so far have had 2 riders – being handed down to my 8 year old and are still ready for more use.
I’d go for the Trek…
