Hmm... I have had lots of blades eventually snap, but they last quite a long while*. If they are 'catching', it could be because too much downward pressure is being applied.
The vast majority of what I cut is hazel, hawthorn, blackthorn and, probably most of all now, ash - in varying states of dieback, from sound to punk. Each requires a slightly different style of cutting and a standard '8' blade has proven best for all of these woods.
But that's just my own experience, different tools suit different people; but I simply don't get on with more saw-teeth on the greenwoods I have mentioned.
*Snapped blades always - for me - go at the base; then they are then fine as short-saws with some teeth snapped off and tape around the bottom. When finally no good for cutting, I reforge them for whatever other purpose.
