What is the difference between this and wood epoxy?

It is a two pack wood filler rather than an epoxy. It is ideal for filling gaps or making up areas where you have needed to cut out rot back to clean wood

Can this fix wood enough to not crack when its placed under heavy strain? I used a different bed filler and it came off after a single use

It depends how much filler and how deep it is applied. The timber to be filled should be 'completely' dust free prior to filling. Don't put the filler in too thickly. Make a number of applications. When the filler is freshly mixed it is moister and adheres to the timber better. If it starts to get a bit stiff it is better to throw what is left away rather than try to use it. It is better to mix up several smaller batches. Best Regards, Rex

do I use primer on wood filler orunder coat

Whatever you would use normally. Just treat the filler as wood.

would this work better than just using JB Weld to build up chipped off corners on a particle board speaker enclosure (i.e. not rot etc.)?

I have no experience of JB Weld so can't comment on the comparison. The Ronseal should work but sanding off to precise corners (once fully dry) will be tedious. And you'll clearly need to paint / spray over afterwards.
