We don't have chest clips on our seats here. And we've never had any problems, we just make the straps real tight (like they should be anyway), and the kids can't get loose.

So let me make it clear, it's absolutely inappropriate to put a 2 or 3 year old in a booster. That's too young and it's unsafe.
You're totally right about not keeping a small child in a booser. But keeping a normal 4-5 year old in a good belt positioning booster is a safe as a harnessed seat taking all factors into consideration. The recommendation in Sweden is to NOT use any harnessed seats for older kids. Leading experts in the field who have been doing this for way longer than anyone else recommend booster ahead of harnessing for kids 4+. I know this goes against US recommendations but that doesn't mean they are wrong.
Anyway, the comparison of harnessing v. booster is irrelevant since any safety difference is small whatever you choose to believe. We shuld focus on rear facing isntead which is where the difference in safety is HUGE.
Using a Swedish, or should I say European seat since all are ECE R44 approved, is technically illegal. That's ironic since it's much safer. Keeping a two year old in a Britax Marathon or Swedish Britax Hi-Way is probably the same regarding safety. The advantage is the ability to rear face much longer, to 55 lbs.
Many kids outgrow seats by height first but that still means rear facing for a long time. And there are many kids who are big kids and are forced to forward face way sooner than desired.
Here, where we live (we are "neighbours"), you would put a kid that has outgrown a rearfacing seat in a booster. The recomendation is clear on not having big kids (3 year olds aswell) in a harness forwardfacing, at all.
The strain on the neck in a carcrash would be to big, the neck would simply snap. (Or get so damanged that the child would die from it later, and I know of so many cases where that happend.) Because the body is totally strapped, and wont move an inch, so the complete force would be on the neck. And the neck of a small kid can't handle it.
So here it is infant rearfacing seat, rearfacing seat, and then booster with the cars 3-point seatbelt.
But like you, we have seats that go up to 55.11/12 lbs (25 kg.) rearfacing, and the kids are usually 4-5-6 years old before they get put in a booster.
We have two 5 year olds rearfacing in Britax Secura
seats. (The tallest is 43.3 inches/110 cm. and 28.6 lbs/13 kg.)
And a 3 year old rearfacing (of course) in a Britax Secura, and also a 10 year old in a Britax Kidfix
