T495s/T490s vs X1C7 Hands On Differences?

[w0qj]

Anyone with T495s/T490s vs X1C7 hands on comparison on the differences?

As a daily user of of X1C3/X1C4 for almost 5 years, I'm shocked by how the T495s/T490s have almost the same physical form factor.
(OK, T495s/T490s is slightly thicker and slightly heavier, but physically close enough with X1C7).

But how does the T495s/T490s hold up under office use, as compared to X1C7?
~1080p LCD of 250+ nits is good enough for us, matt screen preferred.
~Both T495s/T490s & X1C7 have dongle for ethernet LAN.
~Both have internal battery.

Your insightful expertise would be greatly appreciated!

P.S. - I'm aware of a related posting of the theoretical differences on paper, but I'm hoping for actual side-by-side comparison between these machines!
