Recommendations On Brake Upgrades For 2002 Speed Triple

After riding my mates 2017 triple I have decided I actually have no brakes at all on my 2002 ... Is it worth the money to upgrade the discs? Brembo are uber expensive, Armstrong look OK? Also need ideas on which are the best pads for normal street use? My set up is completely stock although I did change the fluid a few months ago, the back brake offers little in the way of retardation... I can either spend a bit of cash to upgrade or just trade the bike in for a newer model...
