Is 160mm to 180mm Rotor Always an Upgrade?

I recently had to swap out my rear TRP Spyre (road) for a Spyke (mtb) and, indeed, it's working much better with my flat bar levers.
NOW, I need to swap out the front.
The cost of going to a Spyke with my existing 160 front rotor is almost the same as getting the 180mm kit that includes a new180mm rotor. I just need to get the 5.00 adapter...

BTW, this is for a rigid, carbon frame "backpacker" / lightweight touring bike. I am 160lbs and will load no more than 40-50lbs on the bike at any given time. The tires used are: 25 x 700 slick, 35 x 700 multi-purpose touring, & 27.5 x 2.1 off-road/knobby.

Can anyone tell me that, aside from the slight added weight, it's not always an upgrade to go to a larger rotor? Thanks very much in advance!
