Rifle Scopes Scope help

Hi guys, looking at upgrading from a vortex crossfire 2 6-18 to one of these options. Looking for some input.
Rem 700 308 26". Shooting moa steel out to 600 and prs hopefully.
Nightforce shv f1 4-14
Burris xtr 2 4-20/5-25
Nikon fx1000 6-24
Athlon ares btr/etr 4.5-27
Vortex viper pst g2 6-24x50
Swfa 3-15

Mrad or moa? I'm used to moa at moment but the subtentions in my crossfire are 1.5, 7 and 11moa so not the most help. Looking to grab around spring but doing my research now. Also gonna drop it into a krg bravo soon. Thanks in advance

Only the PST II and Ares offer Christmas tree rets (Burris if you want to count the H591).
Stick with whatever you want, but resale is typically lower on MOA (at least on this forum).

I would prefer mrad since moving 8mils vs say 25moa would be easier in my head to remember. Most of those come with either. I still need a 1 piece base and 30 or 34mm rings. 20moa needed for 1200 yards and a 308?
