endurance all road sizing?

So I know there have been a lot of topics here about the sizing for canyon, so I hope maybe some owners of the endurance all road could help.

I own a cube tracking bike in the size 54 and I also tried a cube nu road in medium because that’s what the calculator on the cube site said.

For me, the 54 on the tracking feels more comfortable and the medium nu road was just about right when test driving, maybe I also could have tried a Large not sure.

I’ve read here often that canyon sizes tend to be bigger so can I assume that a cube in medium would be a canyon in small?

I would really like to pick the endurance all road because it checks all the boxes and also my budget however I’m a bit unsure because I cannot test drive.

Also my weight is around 95kg at 178cm and I do lift, so I’m a bit of a “bigger” guy – not in height tho lol. so I’m afraid that the small might seem weird for me? Or is this just a illusion 😀

Thanks
