Debating which mountain bike to get 2015 RUSH 2 or a 2015 Anthem 27.5 3

Both of them are the same prices... full suspension entry level sorta stuff. Obvious difference is one is a 27.5 and the other is a 29er. I loved the way the 29er ride and how fast it was, but that was in pavement and not on trails. The 27.5 was very nimble and I could move around it easier... choices. The LBS were bia's since they all rode 29er's. I was wondering should I start with a 27.5 and learn to ride better before jumping to a 29er or vise-versa. First bike not sure which one to pick. Any help or feedback would be great. I choose these two since they were similar in price and rode great for me, but the 29er was exceptional due being a 29er on pavement. What would you choose and why?

 

I'd post in the MTB thread.
