Best map for solo play

I think, it's Storm Point. The areas's are better contained, making it suited for ambush attacks, especially during ring closings. Plenty of height variation for lone snipers. Some squads just go and play with prowlers or spiders for mediocre loot, wasting time, being distracted and making noise, making them easy prey. The gravity cannons provide a better way for transport than the redeploy balloons, because you're gone much faster then risking being hit on the zipline and there's full control of weapons, medkits and shields. And when ambushed on landing you just jump back. Some area's with pretty good loot are hardly chosen for landing, providing a good opportunity to gear up before engaging in fights, like Lightning Rod, North Pad or Fish Farms.
