Well, both have excellent glass and are great choices. I prefer the VX-3 as it is much smaller and lighter, has good eye relief and accepts the alumina scope covers. If you have handled them both you will note that the conquest is much larger and heavier. I like a lighter trimmer scope on my hunting rifles. If you have a larger heavier rifle which you don't intend to carry much, then the conquest would be a great choice as well.
With regard to the cleaning rod, personally I would buy the correct size Tipton rod. I'm sure the rod you have will clean a 30cal, but it will bend in the barrel and could cause uneven wear over time.
