I bought my first board after 2 days of rental board. It's since had 2 seasons of use across 3 different countries, only to be superseded a month ago. Long story short, buy board now rather than having to toil away on shitty rental boards.
Both of those NS boards are pretty similar, I'd go the EVO because it's a bit more playful and the Hybrid camber should give you enough stability to also ride all-mtn / pow. The blunted ends effectively mean you can downsize 1-2cm so the 152cm would probably be ideal for you weight. Although up/down a size shouldn't effect the ride too dramatically.
