Big ends or main bearings difference?

Hello troops, been a while since I've been around the community as car put me in a cream puff. 6month and I'm over it and ready to pick up the tools again and get the scoob repaired.
My question I'd like to ask is this, when our big end bearings decided to give up they tend to knock a fair bit. But usually in my experience the car will still start and run but with difficulty. But how does the car react if it's the mains bearings that fail, how can we decide if its mains or rod bearings that have failed?

I was plodding along after my mot when I got the dreaded knock knock. So pulled over and had a listen and at that point I'd say big ends. Drove on a bit as was on motorway and car lost power then died. And if I try to start it just tries but won't fire. I've priced up full set of both but wonder if I'd just get away with big ends!!!!
Any info would be wonderful.
