I have three crossbows since I moved here from the midwest.
The Scorpyd Orion 150 is by far my most accurate, fastest, smoothest shooting crossbow I own. Definitely my favorite to shoot and kill animals with. However, it is a bit wide, long, and is more difficult to travel airlines with. It is also no longer in production, but Scorpyd does have other bows. I would shoot a deer out to 60 yards all day long.
For airline travel, I much prefer my Ravin R26X. Not as accurate, but accurate enough to kill whitetails out to 40 yards, probably 50. Had a buddy shoot one at 92 yards, but my limit is less. It's short, narrow, crank only. But it's also loud. It also went through cables fairly quickly (less than 100 shots in a year and they broke completely) until I replaced the cable system with Firenocks Pulley System. The R29X is even faster, but more front heavy and even worse on cable life.
Lastly, a Mission Sub-1. Nice bow, but not as fast or accurate (oddly) as my other bows. But, I like it, and the de-cocking feature is great.
Side note: Get bolts that are spine-indexed. You'll really love the improved accuracy, especially with not having to tune fixed blade broadheads.
