Travel insurance isn't just about the flight home...it's about emergency evac to that flight, which might involve say a helicopter or other urgent and expensive care.
Anyway, anecdotal crowd-sourced testimony (including here on FT), web reviews, and my personal experiences with various providers/policies all point to generally very high satisfaction. There seems to be no antagonism unlike with, say, auto insurance.
There are a few policy aggregators out there such as insuremytrip.com. And it's better to start off there as what's offered varies based on residency, country of coverage, etc. I've had success making claims from name-brand insurers offered through these portals.
