Welcome!! I really enjoy my 46mm / 2.0 version. Thing runs like a champ.
My fave apps are Intelicom and watchmaker premium. I paid for both and for me its $7~8 in total well spent. There are some really amazing things being done by the open source communities.
I also like the Regal Interactive watch face. I am not sure why but when voice text-ing, its much faster and more responsive than any of the others I have tried, including the OEM motorola faces.
The other app I use a lot is l.ist its a simple check-listing app. I create a grocery list on my phone, it transfers to my watch and I can grocery shop for items, check them off the list without ever taking my phone out of my pocket. Thats all it does... clean and simple. It does not ask for any additional permissions other than location, if you walk out of the store and forget something on the list it will vibrate and alert you. I have never had a problem with excessive battery usage, or background battery drainage, or data usage... something that can hinder other "smart" apps.
My 2 complaints are voice recognition and the omission of a digital compass. A lot of the Sunnto watch faces have the ability to display compass readings, but they are inactive on my moto 360. Voice recognition can be dodgy at times, especially when there is some degree of ambient noise.
Out of box, get a glass screen protector and consider a strap upgrade. At 22mm lug width there are a lot of options. No reason you have to use the OEM strap or bracelet. I use Zulu 4 and 5 ring straps on mine and couldn't be happier... really comfy!!
