I have two of the MPS400 Flow sensors on my two loops.
The advantage of the MPS Flow is that there are no moving parts.
I think this one is the best to use. (My personal opinion).

Don't get the MPS flow because they don't last and quite some people have leaking problem around the electronic board.
I didn't have the leaking problem but mine stop giving me Flow data after only a few months (max 5 months)
Why didnt you rma?
What I like about the High flow USB version is that the working (hopefully accurate) range is a lot bigger.
I don't have any problems with any kind of noise coming from the sensor, but it has been reported that in certain configurations it can make some noise.
Kind regards,
Boris.
yea i saw that rattling noise also
Have three MPS flow sensors one from when they first came out & not had any issues with any of them... Easy to set-up & I like the size of them... The High flow sensors I also have and as bcikota says have wider flow range, these have also worked well for me & I've not had any issues.. If I do have a preference I guess it's for the MPS sensors for their size & simplicity to set up... Just my 2 penneth worth & personal choice
