The biggest issue I have with the X1 is the volume and the antenna on the remote. I pulled my remote out of my pocket the other day and only half of my antenna was there. No clue when or how I broke it. The TX1000 remote comes with a rubber antenna, similar to what's on my Fury2. Way more durable in my opinion. I know the remote works great at 50 yards or less. I honestly never have tried it any further.
The volume is on a 0-20 scale. In my opinion, it's not very load at 20. I think my Fury2 is loader. I know too load is bad, but I feel like starting the volume in the 14-16 range (roughly 75%) would be comparable to 50% on other calls.
I've got an X24 ordered to replace my X1. I can't say from experience that it's worth the extra money, but I'm pretty confident it will be.
