Looking for "best" non-RTK GPS

Hello.
Can anyone recommend me, what is currently the “best” GPS module compatible with ardupilot.?
I wont use it with RTK. Just standalone.
I want it to work also with L2 frequency (i guess available will be only L2C).
I am looking for most robust GPS out there.
I currently have HERE3 and i want something better.
I have found ZED-F9P GPS, i just have no experience with that one

Thank you for your help.
