I think the default transport protocol depends on the implementation - and
TCP has replaced UDP as the default transport requested by the client on
many commercial unixen, including Solaris, HP-UX, and AIX. (Tru64 5.1 and
IRIX 6.5 use UDP as the default, but are TCP-capable.)

As to "most" NFS implementations doing "only" UDP - maybe if we
include historical implementations, but today, RISC-based commercial
unixen, Linux, FreeBSD, Windows clients and servers, dedicated filers
like Netapps, all have NFS over TCP implementations.
