The Meopta meopro scopes have excellent glass for the price and were considered the secret budget alpha alternative for years. Their low light performance is at/very near the top end as is their overall image quality.
A lot depends on what you are looking for with intended use. They are based on a 1" tube that reduces overall weight, but also won't have as much travel as larger tube scopes. The reticles offerings are fewer, generally simplistic, 2nd focal plane only, and cater more towards hunting. They don't have as robust turrets for dialing like you'd find in a NF, but they are effective and work. Never had an issue with holding zero (but I also haven't dropped one). NF generally caters more to the tactical/long range group offering a stout scope where lots of dialing or 1st focal plane is preferred.
From a comparison standpoint, the Meopro is similar optically to a Swarovski Z3, a Zeiss Conquest V4, Leupold vx5hd for image clarity/low light performance comparison with current offerings. I own a few of the Meopros and they are awesome for lightweight hunting setups for me.
