Older X-T10 or a newer X-T100? Help decide please

Thanks for the knowledge, I myself lean towards x-t100 just because it's just newer. I understand the differences in both the old X-T10 and the newer X-T20 (I clearly read all reviews, opinions and specifications of these models) and the differences in image processing (bayer vs x-trans). I just want to confirm that I'm doing right. For traveling, it is very interesting for me to be able to charge the X-T100 with a USB cable and bluetooth that certainly does not take the much needed energy for a digital nomad. Yes for sharing photos I can use wifi, PC and power converter in my car but why not use bluetooth, phone and power bank.

I looked at examples of photos from older 16mp sensors (eg here on DPReview) and I don't know why but they all seem to me more grim than the newer 24mp X-T100. As if they were (as opposed to 24mp) all shot under the cloud. They simply don't have as much color, contrast, range dynamics, and maybe even sharpness. And as I say it's just a "nice" jpeg output from the camera that interests me.

Thanks also for the opinion on Samyang / Rokinon - I think this is a reasonable choice and sufficient for travel photography. What worries me a bit is the choice of a set lens. I'd like one autofocus lens to have. Probably I will avoid 18-55 in the case of X-T100. I'd have to buy it separately and use it and I'm a little worried about a bad copy. It is clear to me that these will be full of ebay. On 15-45 I like his wide range, but he's bad on his second range. Zoom Motor Movement - I remember it once on an old minolta lens. It will not be a problem to shoot static objects. And there is an XC16-50 with a very reasonable price (eg at auction) ...

Even for M42 adapters. I think "any" on fuji will be better than some for nikon with special "inner lens" for infinity focusing. I probably didn't get lucky for a good piece, but it always reduced my lens quality...
