You'll get extra 200 points for monthly ranking (equal to winning at boss node in 5-4 for 100 times) as well as "medal" which can restore some resources at will if you managed to destory the gauge. And... being top ranker will grant you some new items for next month, that probably won't be able to get in usual way within 3 months. So it's not a waste to clear 5-5 if you have the ability to clear it.
