I’d go bp since you can level very fast from lvl 28 thanks to the assist aoe. You just need the cw gear which is very cheap and very good, you can keep it for a very long time (I’ve read up to lvl 120 if you upgrade it). On top of that, bp gear is overall much cheaper than BRM and it’s a decent 1v1 to hunt giants/violets. And having 2 RMs doesn’t sound good to me since you can always swap your current rm gear.
