I did not buy one actually, but I narrowed also to the eleshop litevna 64 some times ago ...

It's a question of whether you want to spend around €50 or around €200.
More expensive is usually better. The question is what you need and whether the extra cost is worth it for you.

I don't really need to ask the forum for the tip: "buy the most expensive one".  ;)

It's a question of frequency range. Up to 300MHz -> 50€; Up to 6GHz -> 200€.

Sure, that too, but doesn't the 50€ version go to 1.5GHz?

If you know that you need 6GHz, then buy the 6GHz version.

Indeed, the model depends what you are trying to do.
Bacon radio or ham radio, 300 MHz is plenty.
Sub-GHz radio, test equipment like oscilloscope probes, coax cables, then the 1.5 GHz model is recommended.
More modern digital radio interfaces work in the~3 GHz bandwidth, so the 6GHz LiteVNA model makes sense. It's 4x the frequency for 4x the price, which is a very good deal. To put it in perspective, I paid more just for a calibration kit for a "proper" VNA in the past.
And while these units are not going to give the same dynamic range (decibels) as standalone units, 30dB of noise free range is plenty for anything antenna related.
