I'm more of a CHR buff, so would say:
TFM Radio from Jones TM (the original and many res-sings).
or
Wise Buddah Contemporary Cuts (for Radio Aire, Viking FM, Exeter FM etc).
I know a lot of people who appreciate production quality and detail will slate the latter for heavy use of synthesisers, however I quite like that and think that the package has proved it's adaptability for stations that don't have the jingle budgets the may have had before such high levels of competition.
I'm not a great fan of The New Pennine FM package unfortunately. In that neck of the woods would prefer to listen to the new UTV package on The Pulse.
