Can rebates actually make hfm competitive when comparing it head to head with another broker

I’m at a decision point and I want to think through this clearly. I’m currently using HFM but I keep getting curious about other brokers. The issue is that every time I compare fees on paper, the numbers look different depending on whether I factor in GlobeGain rebates or not.

Here’s what I’m trying to do: I want to compare HFM to another broker I’m considering, but I want to make sure I’m comparing apples to apples. Both have different spread structures, commission models, and one of them integrates with GlobeGain for rebates while the other doesn’t.

I’m worried I’m either undervaluing what GlobeGain rebates actually do for my total cost, or I’m overestimating their impact and fooling myself into staying with HFM when another broker might genuinely be cheaper.

How do you actually structure a fair broker comparison when rebates are part of the equation? What’s the clearest way to calculate which one really comes out cheaper for your actual trading style?
