Best Z-Wave thermostat available today?

After using the Honeywell Z-wave thermostats (TH8320ZW1000 aka YTH8320ZW1007) for years, I've been helping out a non-profit with automation and they picked up the cheapest option available from eBay, the RadioThermostat  CT22/CT32 thermostats, and have run into a bunch of weirdness with the RT thermostats, especially their lack of instant status updates and their odd idea of what an "Energy Save Mode" means.

Anybody using the newer Honeywell T6 or another Z-Wave thermostat and happy with it?

I use the Stelpro Z-Wave thermostat but it's for line voltage applications and doesn't support fan forced heaters.  Which for me is fine as I have baseboard heaters.  Currently Stelpro is the only option (I know of) for line voltage 240v baseboard heaters that I'm aware of that is Z-Wave.

The Stelpro is interesting;  we tried one out for a Hydronic heat zone, but it didn't actually produce any heat-- Stelpro's "Variable heating" means it only works on resistive electric line-voltage, not fans or pumps.     

We ended up using a CT32  after converting the line-voltage zone to 24VAC (using an Aube RC840T).

Yup, which is why my bathroom heater is still using the knob thermostat and nothing better.  I'm still hoping something better comes out but there just isn't much for the baseboard market arena.  The Stelpro at least gives me the ability to monitor/manage the temp in the different rooms.

Bathroom line-voltage heaters are difficult.    For anything else, there's usually a good place to hide away a relay adapter like the RC840T-240, but usually bathroom controls are just mounted on a single-gang box.

The single bathroom heater (fan forced) may be the only candidate I would spend the money on an Aube for just to put a thermostat on.  The other option I have contemplated was using a heavy duty relay like the one from Aeotec to control the power to the heater and then using a remote temp sensor.  All in all though putting in an Aube relay is just easier though :)
