It's a tough call! Most of us are not lucky enough to have money and / or space for both. Doing so is considered one of the lucky ones.
They are obviously two different types of machines that have a very different fan base. In general, but certainly not all the time, arcade machines tend to have a couple after their counterparts in pinball.
But the most important thing to remember is what goes well with the machines. How does the game fit the decor of your home.
For example, arcade games tend to go very well with a room that has more than a university environment. Should the university, as well as banners of ping-pong table, big screen TV, etc..
Pinball machines are more sophisticated (for lack of a better word) vibration. Give the impression that one style bachelor pad. Perfect for a games room with darts, pool, etc..
Pinball machines also work perfectly with the decor of the house. For example, if you put in an arcade game room or living room that tend to stick out like a sore thumb. Meanwhile pinball machines can work under the right circumstances.
I do not care who you are. See an old pinball machine from the 1950s into someone's home only adds an element of "cool." Like an old hanging on the wall, that really adds much charm to the presentation of a home.
