Just got my ThinkBook 13s. Love the size!
First impressions I am impress with it. However coming from T495, hands down Thinkpad is still the way to go. For starters the keyboard is not as nice and the display not as nicely calibrated as the T495 (there seems to be some yellowish tint on mine), but all is fine and nothing to worry about. If you use iphone, its sort of like TrueTone yellow tint. Also the display on the T495 seems to scale better, not that there is anything wrong with the display of the Thinkbook 13s, just when you compare to thinkpad, thinkpad is better no doubt about that.
The trackpad is nice to use compared to the T495, one other thing about this Thinkbook is the arrow up and down is really small, so keyboard wise, its nicer on the thinkpad as you have a full size keyboard. Having said that, this thinkbook keyboard is nicer to type as it doesn't require as much push to the button as the T495, meaning when typing it is softer to use.
Here are the brand and model of the display, RAM and SSD (using hwinfo64 software). I believe they are all similar for our batch:



Here's some comparison of ThinkBook 13s and T495 (although the pics seem like no size difference, the ThinkBook is actually much smaller and slimmer compared to the T495):
