I recently bought the SeeSii nanoVNA-H4 which has a 4" screen. I love the larger screen. It is useful up to 1.5 GHz, but my use for HF radio is just 3 to 30 MHz, plus VHF and UHF, so this is fine for me.
If you look at the nanoVNA menu structure map you will see that the H4 gets you some useful additional functions, including two more memory locations and 201, 301, and 401 sweep points options. The extra sweep points come at corresponding increase in sweep time, however.
As with all of the nanoVNA units, however, it is best to remember that the basic nanoVNA circuit design is open source, and you are getting what you pay for. Chief concern is component quality, shielding, and soldering.
