Virginian,
If you would like to find a reason for buying the Trance E+ 3, it is the motor. 70 (Stance) vs. 85 Nm (Trance) for the hills means a lot.
I understand you have ridden MTBs for years. Just let me tell you using an e-MTB for commuting is not the best of ideas. I used to own a Trance E+ 2 Pro and that e-bike just hated the pavement. I had to change tyres to all-rounders. I had to fit a rear rack (and there are very few of them good for an MTB). Giant trail e-bikes are Class 1 (you don't need some speed on your commute?) Why would you need Full Suspension for the commute in the first place? Additionally, riding the Trance E+ on the pavement made me very tired! An e-MTB does even not have a kickstand!
In my opinion, you better look for a proper commuter e-bike, equipped, with a strong motor (85 or 90 Nm) and a decent 11 or 12 speed cassette. On many mid-drive motor systems (except Bosch) you can fit a small MTB chainring for improved climbing steep hills...
If you must buy a FS e-MTB, the Trance E+ has not only a stronger motor. It is just visually gorgeous
