I love the TBM as well and fly it the most in sim. Also understand how others have mentioned its similarities to the TBM but it is a popular choice in its price point. Its cross shopped with the TBM and Vision Jet (plus I just like turboprops).
The E1000 has better performance (admittedly some are marginal) over the TBM. Specifically top speed, max cruise altitude and climb performance. Agreed on what you called out as well, another big thing about the E1000 in the cabin is the continuous pieces of glass in front of the pilot and co-piot versus the TBM. Realize there are similarities, but Lionheart has been working on it for awhile so I hope them or someone else releases it soon.
