Urchin Underpass is my least favourite at the moment but my preferences otherwise really vary depending on whether playing turf war or splat zones.
I use the Aerospray MG which is brutal up close but has terrible range which was really hard to manage on some of the more open maps but I've found strategies to overcome this now on most maps.
Give it time you may find strategies or even just a charger which subs/specials that work better on that map.
BTW, bring on the ability to change your load-out between matches.
