I have both of them, I usually keep my 7x28 on my car, they are very bright for their size and they have dielectric coated prisms, and ED glass.This really makes a difference. They are a good investment. On the other hand, the 6x30 are amazing, they also have ED glass and dielectric coated prisms, they are very easy to focus and the have a large sweet spot. They are stable, you can hold them with one hand. Ideal for bird watching in wooded areas. They are worth every cent I paid for them, they are rugged, light and are a pleasure to use.
These are in another level if you compare them with the 7x28.
I ended buying both of them because I read stelar reviews about them. Maven Optics are very well known in the hunting community.
I have gravitated into smaller sized optics that offer me good views without the weight penalty.
I also own an upgraded Swarovski 7x30 B SLC that have become my favorite binoculars.
I hope this helps
