I don't say this from experience of NX-OS release 7.0, but unless you need feature or platform support that this release provides I wouldn't use it. The release has only been out a month or so, and given the number of new features that have gone into it, there's plenty of opportunity for regression bugs to creep in.
The NX-OS 5.2 release you have is pretty good, and it's also a long lived maintenance release so it will have support from Cisco for some time yet. The only thing I'd say is that if you're going to stay on NX-OS 5.2, then consider an upgrade to the latest release of it i.e., 5.2(1)N1(7).
We've been using 5.2(1)N1(7) across a number of switches supporting FabricPath, vPC, vPC+, FEX etc., and so far haven't seen any issues with it. We moved to this release a while back as we got hit by CSCty86291 MTS buffer exhaustion with sequential add of large vlans that's in all releases . This was seen a couple of times when pasting VLAN configuration, a change that you would consider low risk.
I put a couple of 5548s in using NX-OS 6.0(2)N2(2). They've been running fine for the past 4 months supporting about 500 devices as core switches in a mid-size office building.
I initially used the 6.0(2)N1(1) they shipped with but was hit by bug CSCug46504. It prevented wireless APs from getting addresses (and the DNS server necessary for them to register with the WLC) assigned via DHCP
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
