Stainless Chimney Liners

Im looking at getting a stainless flue liner in conjunction with a new gas steam boiler.  Ancient tile liner is definitely failing and something needs to be done.

There seem to be a lot of different types of stainless liners (corrugated,  flexible smooth wall; rigid, heavy wall, etc) and not a lot about when you should be using one type or another.  Anything to avoid, push for, or am I overthinking it and should just trust the chimney inspection company’s recommendation?
