I just replaced it with an Ecobee 3 that a family member gave me. I will say, the Ecobee is a nicer, more modern looking tstat, and has a lot of nice features. The remote sensors are great and really do help keep your home more comfortable if you have more than 1 story. Certainly more full featured than Sensi.
I do not have direct experience with Nest, however, I did work in the smart home/HVAC space for a while, and I will tell you that customer feedback on Ecobee is much better than Nest, and to me, Ecobee's features are much better. That may have changed, haven't kept up with it.
If I were to direct anyone to any of these choices, I'd go with the Ecobee.
Emerson Sensi has batteries. I installed it without C wire about a year ago. Works fine and still showing full battery.

There are 2 different Sensi's here - the Sensi ST55 which is the white model for free ($0) and the ST75 which is the touch model that costs $25. Here in CT only the ST75 is available (for the same price through eversource). AFAIK the ST75 requires a C wire.

My one annoyance (and confirmed on Android and iPhone) is that Geofencing doesn't work well. It's also not adjustable, you only have 1 option to have it go down 3 degrees when you're 3 miles away. If you live close to work, that's not good. Not that it matters because it won't sync in the background anyway, you actively have to open the app and let it update your location (it's not a location preferences issue on my phone, it's the app being dumb). Kinda defeats the purpose if it's not automatic. In my previous experience Nest works much better in this regard.
But honestly, if you're missing a C-Wire and are in a temporary housing where it's not worth the bother investing into getting a Nest or Ecobee properly set up, then this is a pretty good solution. You can probably even get away with it in a rental and just leave it when you move out.
For heat/cool systems, if you don't have a C-wire, the unit attempts to circumvent that lack of power by cycling on/off very briefly all the time to keep the unit charged. It's not an ideal situation, and many have complained of long term reliability.
If you turn off WiFi on the Sensi, you can use it with just battery power. But then it's a dumb thermostat.
