I voted for [name_u]Owen[/name_u] [name_m]Matthew[/name_m] because I think it fits better with big brother [name_u]Bryce[/name_u], but I also like [name_u]Sullivan[/name_u] [name_m]Matthew[/name_m] too. [name_m]Callum[/name_m] [name_m]Matthew[/name_m] is my least favorite of the three. It’s a nice name, I just don’t like the flow of the m at the end of [name_m]Callum[/name_m] and the m at the beginning of [name_m]Matthew[/name_m]. Good luck! 
[name_u]Owen[/name_u] & [name_u]Sullivan[/name_u] are both adorable. I voted for [name_u]Owen[/name_u] as that name slightly appeals more to me, probably more to do with my DS making me watch Jurassic World 1000 times lol.
I love the name [name_u]Sullivan[/name_u]! I think [name_u]Owen[/name_u] probably matches [name_u]Bryce[/name_u] slightly better, but I still prefer [name_u]Sullivan[/name_u]. I like [name_m]Callum[/name_m] a lot too, but the m’s in [name_m]Callum[/name_m] and [name_m]Matthew[/name_m] run together a little.
[name_u]Sullivan[/name_u] [name_m]Matthew[/name_m] is definitely my favourite. [name_m]Callum[/name_m] [name_m]Matthew[/name_m] is also really cute.
I voted for [name_u]Sullivan[/name_u] it’s one of my top boys guilty pleasure names (though it’s only a guilty pleasure for me because of my first choice for boys I think it works well). My second choice would be [name_m]Callum[/name_m] though I find that and [name_u]Owen[/name_u] pretty dated.
[name_u]Bryce[/name_u] and [name_u]Owen[/name_u]!
I think [name_u]Bryce[/name_u] and [name_u]Owen[/name_u] are perfect together. I like your other two choices as well, but as others have pointed out, the end of [name_m]Callum[/name_m] and the beginning of [name_m]Matthew[/name_m] run together, and I personally think [name_u]Owen[/name_u] & [name_u]Bryce[/name_u] are a little better matched than [name_u]Sullivan[/name_u] & [name_u]Bryce[/name_u].
