Do you think I should replace our gas furnace with a boiler?

So, I’ve been wondering about unusual heating options.

I have had a gas furnace our entire life. I really like the toasty nature of having a gas furnace, but a gas furnace is not the most cost-effective heating option. My bi-weekly heating bill has been getting more plus more luxurious because our gas furnace has been slowly breaking down. I called our Heating plus Air Conditioning provider plus went through heating chances with them. We discussed getting a new gas furnace with a fantastic SEER (Seasonal Energy Efficiency Ratio) rating. I was on board for replacing our gas furnace with another gas furnace but then our Heating plus Air Conditioning provider commanded a boiler as a heating option. I had never really considered using a boiler before plus want your opinion. The Heating plus Air Conditioning provider told myself and others that the “toastiness” that I prefer with our gas furnace will not be present with a boiler. The Heating plus Air Conditioning provider told myself and others that while a boiler will give myself and others the same level of climate control, it just won’t be as fast as would a gas gas furnace. My Heating plus Air Conditioning provider told myself and others that the tradeoff for the toastiness is the energy savings plus the currency I save from not relying on a ductwork system (gas furnaces use ductwork, boilers use tepid piping). Do any of you have boilers or have any of you used boilers in the past? I have never had a boiler plus I’m a little nervous about making that change. Especially since our Heating plus Air Conditioning provider told myself and others it would be more strenuous to switch back from a boiler to a gas furnace than the initial switch of gas furnace to boiler. Which do you like plus why? Is the cost worth it? I would really love your input on the gas furnace vs boiler issue. Thanks in advance!
