What do you think of these travel management platforms?

I’m looking at travel management platforms and trying to get a better sense of what actually works well day to day. G2 highlights a few that seem promising. Does anyone have experience with the tools below?

Navan (Formerly TripActions)

It combines booking, expense tracking, and travel support in one system. This seems like a practical choice for teams that want built-in controls and fewer emails.

myBiz by MakeMyTrip

Tailored more toward companies operating in or with teams in India. Offers policy tools, GST compliance, and access to a wide range of travel inventory.

Brex

Known primarily for spend management, but now includes features to book and manage travel with company cards and controls built in.

Ramp

Another finance-focused platform adding travel features—automated expense tracking, easy approvals, and booking within company policy seems to be a core strength.

Amex GBT Egencia

A more established name in corporate travel. Offers global coverage, policy compliance, and reporting for companies with more complex travel needs.

I'd really appreciate your feedback if you’ve used any of these or decided to go with something else.
