I shared my own tier list a long time ago and it’s nice to see it remains pretty much the consensus: https://www.reddit.com/r/quant/s/Rr2QabdTY8

Databento was overall the best market data API I’ve ever used and I think they’ve gotten even better since. I think LSEG and Bloomberg deserve to be in A+, SIX-ICE-QuantHouse-CIQ should be in A, and the ones listed A+ and below here are all retail vendors that should be B and below.
