Would you rather work for a brokerage like CBRE/JLL or Nest Seekers/Douglas Elliman

The commercial side will be more transferable and build more relevant skills for non industry jobs.  With that said if you are set on RE borkerage both can be very rewarding opportunities.  On the commercial side you have fewer "rockstar" brokers who can close large deals alone as most work within a decently sized to large team.  The CRE side interacts with institutions on a regular basis opening up new opportunities.  I would say while income is technically uncapped, it is more restrained on the high side than residential is if you are working in the luxury to ultra luxury market.  On the residential side in the luxury and ultra luxury market you get to work closely with very wealthy people and their represenatives very closely.  Your ability to make deals work is more flexible as well as there are many ways to pitch a deal.  Your income is less restricted as you can more actively negotitate compensation structures with developers and sellers than you can on the commercial side.  Direct teams generally are smaller thus the commission is split fewer ways.  On the flipside there are less guarentees as most of these jobs are 99%+ commission from day 1.
