Boutique firm vs National brokerage, for new agent

[Eugene Kravchenko]

I am a new licensee in DC area. I have interviewed with large brokerages and few mom and pop shops that deal is rather luxury segment. While big firms offer 65/35 splits and training, the mom and pop shops offer 25/75 on the listing side and 50/50 on buyer side, but they offer small shop setup, and mentoring/hand holding and handful of agents. I am a hands on guy. Would mentoring for such a large cut be more benneficial vs large firms? Thanks
