I have both, and I don't see either going anywhere. I've actually had Twilight Zone for over 10 years now, and I never get tired of it.
Dialed In has a bit more of a challenge to it on standard setup. Getting to the wizard modes is a much harder task and collecting all the SIM cards requires a lot of precise play. Twilight Zone has a bit more variation to it, but after owning it for a while, you'll find getting to Lost in the Zone isn't all that hard (though you'll be skipping modes to get there).
Both games are very casual friendly because someone can step up, flip around, and see fun and cool stuff. For a serious player, both games can also be set up to be quite hard and challenging, yet still fun. My TZ is set up so brutal that it humbles the best players in our league quite often.
Either game will provide a very noticeable change of pace from your Star Wars, and either one would compliment it well. I don't think you would have trouble selling either game for what you got into it if you find that it's not what you were expecting. But honestly, you can't go wrong with either game. Dialed In is the best new game in years, and I consider Twilight Zone to be the best game of all time. It's a true win/win scenario either way you go.
