I have been in the same boat for a while, I've had several different scopes from dnt and hicmicro and been searching for "the one". Been watching and waiting for these scopes to come out and seen them at the shooting show etc.
My Alpex 4k, I sold to help fund a rifle at the time but now I've just purchased another one....

AE50lrf model. For a 223 foxing set up, I've decided it's currently the best dedicated scope that's easily available, and isn't going to be beat at night by anything newer yet.
To prove this, watch sone new YouTube footage that's out comparing the Alpex 4k and pro at night. (Bang to bite) Is the channel name. The pro is built for day use and does ok at night, but the 4k I believe was created for the night. No ai algorithm can compete with the larger lens when darkness really falls.
I still may get a pro-model for a stalking rifle in time. But for foxing I'd advise you stick with 4k.
I had been using the previous alpex 4k on the 223 in the past, but then changed for the lighter Zulus V2. It is certainly a great little scope, it's now going to try out life on the 308 next. It's superior to the Alpex 4k in daytime, brighter images, doesn't struggle with the contrast of a shady hedge row below a brighter sky above etc. But at night it's inferior overall, yes it can yield cracking images out to 150/200 yds and beyond if conditions are perfect. But so often conditions aren't perfect and the larger lens of the Alpex just does a better job at longer range work especially when there's a bit of moisture/ humidity in the air. It makes better use of the IR and doesn't get washed out so easily. I use the Sirius IR and it is very good.
Yesterday I could of ordered a Zulus 4k, I could have pre-ordered an Alpex pro, instead I ordered a replacement Alpex 4k. All the new ones I believe share the same 50mm f1.8 lens as the Zulus V2, a good all rounder but the f1.2 of the Alpex 4k wins at night.
