Looking for Slider with 3 axis motion controller. Advice needed

I´m looking for an slider with an 3 axis motion controller.
After an search the internet, two products are looking interesting for me:

The
Sapphire Pro Ultimate Trekker Bundle with Stage One PLUS Slider (http://www.dynamicperception.com/SapphirePro-Stage-One-Portable-Time-Lapse-System-p/bdl-1-vx3pro.htm)

and the new
Genie II Pan Tilt Linear Kit with an magic carpet CF carbon slider (https://syrp.co.nz/products/genie-ii)

Both systems offer lightweighted and length-customizablöe tubes, so you can carry them easier and adjust the needed sliderlength.
The DP slider needs more attention in usage, the Syrp seems to be more easy to use.
The pricing will be nearly identical.
The benefit from Syrp would be the availability here in Germany, the DP slider will be shipped from the US.

Does anybody have some experience in the DP slider, or has used the Genie MK I ?

Which offers more versatility? Which more stability and reliability?

Thank you for posting your experiences
