Which dog do you surmise is best for me?

I am getting a dog for Christmas I don't know if i should get a boston terrier/boxer or a Chipom
Unless you're getting them from a shelter, you shouldn't get either. Responsible people do not breed mutts and responsible folks do not sell dogs for Christmas.
I hope you are getting them from a shelter. A boston terrier/boxer mix would be larger and short haired, but how they got that breed is a mystery- the dogs aren't exactly compatible. A chihuahua and pomeranian mix would clearly be smaller, but no telling what the coat would be like and the temperaments on both would be a crap shoot. Don't buy them from a "breeder" because no worthy breeder would sell mutts.
I think you should receive a boston terrier/boxer because their big dogs not a chipom.
I can't help you on what dog to get, but it depends. If you have kids and whether your active. If you have kids get a friendly pet or whether you want a protector and a running partner get boxer. My decision. Look on internet about dogs. it adjectives depends on you.
A Boston Terrier and a Boxer are both VERY different dogs and I'm not even sure what a Chipom is? Is that a "designer" breed (i.e. mutt that folks are paying)? First, getting a dog for Christmas is a bad impression on so many levels I won't even go into it here (would embezzle too long), second... if you haven't decided on the breed and it's 3 weeks until Christmas I own to ask have you searched out reputable breeders? Have you interacted with dogs of these breeds and spoken to breeders something like what they are like? Are you well versed on how much care, training etc. respectively may need? Boxers are wonderful, but I would not recommend a Boxer for most first time dog owners.

If you are planning on rescuing a dog talk to the folks at the rescue... if not I would DEFINITELY hang about until after the holidays and do my homework first.
If you look up Animal Planet Dogs 101 and click on dog resources
there's a breed selector quiz. It will give you characteristics of different breeds.
Why don't you simply have a surprise.
You gave absolutely no information about your life-style, how the heck would we know?
Answers:    Well it all depends on what your identity is like. Boxers are very lovable, playful dogs that are always in place to sit in your lap, take a forty winks with you, or play. My boxer especially likes to play hide from view and seek and tug-a-war.
