Likewise, no FFT of any kind. I even emailed the company earlier this year and verified that it had none of those features, although they indicated that they are planning on adding them. If/when they do add an FFT you will need to look closely at how long it is. For example, according to the user manual the 8-bit vds3102 only has a 2k FFT so gives only 1k frequency bins, even though it has 10 MSamples of memory.
I have downloaded both the vds3102 and vds6102 software, and the features line up with the documentation. No math menu of any kind on the vds6000 software, and the vds3102 software gives you no choice of any kind for the FFT length. It is fixed.
So even if the 14-bit hardware is great, if you want to do anything more than just look at waveforms and do basic measurements on them you will need to write your own software and just use the scope as an acquisition system. For me it was a deal-breaker.
I ended up on Ebay and managed to pick up a used (and out of production) multi-resolution Picsocope 5244B for $457 US delivered.
By the way, which 8-bit picoscope were you looking at that was priced that high? They have a ton of models.
EDIT: Hi Balzannar. I just realized that you started this thread - surely as part of your quest to find a quiet scope. It looks like you are going down the same path I did earlier this year. good luck!

Can you use generic oscilloscope software with the Owon? Eg.

Actually, there has been a 24-bit scope for sometime now - the National Instruments 5922 in PCI of PXI interface. It varies its bit-depth between 16- and 24-bit, with sampling rate between 15MS/s and 500kS/s. So while it is extremely quiet with a noise floor at about 6µV, it's really more suited to being configured as a data collection VI or frequency domain work, not time domain as a scope is often called for. What's more, if used with an interactive UI like NI's InstrumentStudio running on their controllers, be prepared to wait as you crank those virtual knobs - it can be painfully S L O W. Not cheap either.

I don't think the softwares will work with owon scope.
For REW I will use hi res sound card

Math function is available. You can do - + * / with both channels
FFT also availale, but I think Owon should not give the function as it so useless

That is not 2 mV, it is around 200uV RMS which is more normal.....
This is amount of noise that, for instance, has Rigol DS1054Z (unlocked to 100MHz) that is an 8bit scope.
It is still not low noise but OK. Low noise would be quite less than 100uV RMS. There are quite a few inexpensive 8 bit scopes (Micisg and Siglent comes to mind) that have much lower noise than that.
So Owon is 14 bit but noise levels are at just OK-ish entry level 8 bit scope level.. And it is not even that inexpensive.
For general purpose work, DS1054Z (or Micsig or Siglent) would be better choice overall..
