Both your solutions will do the job. You didn't print as requested in 2.6, and you didn't mention the jobs' statuses. What status would you expect them in?
Use kill -9 only as a last resort for otherwise unaccessible processes. Usually, the default 15 (TERM) is sufficient. And, you can list several processs to kill in one command.

KILL(1) General Commands Manual KILL(1)
NAME
kill - terminate a process with extreme prejudice
SYNOPSIS
kill [ -sig ] processid ...
kill -l
DESCRIPTION
Kill sends the TERM (terminate, 15) signal to the specified processes. If a signal name or number preceded by `-' is given as first argu-
ment, that signal is sent instead of terminate (see sigvec(2)). The signal names are listed by `kill -l', and are as given in
/usr/include/signal.h, stripped of the common SIG prefix.
The terminate signal will kill processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot be
caught. By convention, if process number 0 is specified, all members in the process group (i.e. processes resulting from the current
login) are signaled (but beware: this works only if you use sh(1); not if you use csh(1).) Negative process numbers also have special
meanings; see kill(2) for details.
The killed processes must belong to the current user unless he is the super-user.
The process number of an asynchronous process started with `&' is reported by the shell. Process numbers can also be found by using ps(1).
Kill is a built-in to csh(1); it allows job specifiers of the form ``%...'' as arguments so process id's are not as often used as kill
arguments. See csh(1) for details.
SEE ALSO
csh(1), ps(1), kill(2), sigvec(2)
BUGS
A replacement for ``kill 0'' for csh(1) users should be provided.
