The #4 reticles generally stand out more in low light, but be careful with Meopta as their #4 center lines are fairly thin. The outer lines are nice and bold, so you can bracket the target somewhat. I believe the VX-3i have an etched reticle (not sure on this - at least in terms of the duplex), which in my opinion seem to hold up in low light better, but I haven't used my 3i in hunting situations yet so can't comment on it.
If you can find a Conquest with a #4 reticle, that one as very bold and about perfect. I had one and swapped it this spring, and have regretted it ever since.
All that being said, to my eyes, my Meopros are brighter than my VX-3i.
