Price ridiculously wasn't something I considered, once that out of the way it was mostly aesthetics, customisation, reliability and repairability.
I preferred how chucky the UHK was vs the ErgoDox kits. Also preferred the hot swappable mods you can take in and out of the UHK were pretty compelling too. These are all listed here: https://ultimatehackingkeyboard.com/shop
Though admitedly, I haven't swapped them out once since I settled on what works for me.
The UHK has a strong community behind it's parts, and speaking from sone one who can and does spill even the best unspillable coffee cups.
The risk of me breaking the UHK is a lot closer to an unacceptable number than zero. And being able to swap out coffee broken parts is easy with UHK.
Erodox and ZSA easily could have been too but I couldn't find as strong of a compelling argument as with the UHK. It was more likely a coffee rinse of the Ergofox or ZSA keyboards would mean buying a new one which meant the upfront cost of the UHK was in some part, insurance against my own clumsiness.
The customisable and awesome software that came with UHK was very high up there too but I got the impression those features were almost as prominent in the competition too.
