Pulsar Apex XQ38 LRF vs ATN Mars HD 640 1-10x 19mm

I can't stretch to a new version of one of the better thermal rifle scopes but I've found these two second hand for around £1,500 each.

I will mostly be using it for rats on a sub 12 f/lbs Walther RM8 but may try it on a .223 for foxes later.

So, the question is, which would suit my rat and fox requirements better?

I know the LRF would be a benefit for the ratting because of the pellet curve but I can't figure out which of these units has the better image and how much difference there is between the two at rat ranges firstly then potentially out to 120yds if I use it for foxing.

I'm stumped! Vid recording on the ATN vs LRF on the Pulsar is a fair trade so that just leaves the image quality unless I've missed anything obvious.

Thanks in advance for any thoughts / advice.

Pulsar every time
Apart from ATNs terrible reputation for reliability and service, a 640 sensor with a 19mm lens is a pretty dumb combination
As for image detail, simply divide the pixel size (17 microns in each case ) by the focal length of the lens (38 for the Pulsar, 19 for the ATN)
The smaller the answer the better
So, for the Pulsar 17/38 = 0.447
For the ATN 17/19 = 0.89
In other words, the Pulsar image will have twice as much detail as the ATN

Thanks Bruce. Much appreciated. That's enough for me.
