Currently own Kinesis Advantage 2. What’s a good step-up for low profile ergo split keyboard?

SliceMK has an ErgoDox variant that is wireless and low-profile using choc v1 switches. Disclaimer: I've been daily-driving one of their ErgoDox Wireless Lite keyboards for about 9 months. But I like the ErgoDox physical layout -- been using one on a nearly daily basis for the past 9 years.
