Capital markets vs Investment management

This is going to be a relatively generic question / post, but hoping to spark a conversation:

I am close to taking a new role - for some light context, I have between 3-5 YOE (2-3 in a true CRE investment role) in a major market at a mid-tier CRE investment manager. There are 2 prospective offers on table, similar as far as title, both will be a "senior analyst" with promotion to associate possible within a year (performance dependent of course). One on a major capital markets / investment sales team (think CBRE, JLL, CW, Eastdil) and the other at a well-regarded institutional investment manager on their acquisitions team with a relative focus on indirect investments (Hines, Heitman, Starwood, Stockbridge, Equus, LaSalle IM, Singerman, Greystar). 

I've spoken with mentor & others in network and general feeling is the investment manager is a great job and a fantastic opportunity that should not be passed up, and that I could jump over to brokerage easily if I so desired down the road. My goal for a new position at start of search was to land a more transactions focused role with higher volume (both would do so). I realize that a top IM would be an exit from a capital markets team - yet I have always had interest in the brokerage space and feel that the combo of being in the numbers but also maintaining a client facing attitude would provide the work environment I desire at this stage of my life (mid - late 20s, that's all the detail I will give about personal life, assume whatever you like). 

Would love to get people's thoughts on general WLB, exits, experience gained, general culture in the space, etc. (any comparisons or contrasts you'd find helpful) I realize a lot of this is team, market, asset type specific - any general feedback / constructive conversation would be helpful and appreciated.
